Chest pain can be the result of multiple issues, including respiratory problems, digestive issues, and musculoskeletal complications. The pain can trigger cardiac issues as well. Not all pain that is felt is associated with the heart, but it should not be taken lightly either. Symptoms can be different depending on the cause of the pain. While cardiac issues cause feelings of sudden pressure in the chest or a crushing pain in the back, neck, and arms, pain that is felt due to noncardiac issues gives a burning feeling along the digestive tract or pain when deep breaths are attempted. Different people feel pains differently for the same condition.

Thorax | Pain
The word thorax comes from the Greek θώραξ "thorax" "breastplate, cuirass, corslet" via .
Thorax | Etymology
The thorax or chest is a part of the anatomy of humans, mammals, other tetrapod animals located between the neck and the abdomen. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the creature's body, each of which is in turn composed of multiple segments. The human thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain.
Thorax | Introduction
"Thoracocare" is derived from the Greek θώραξ (thorax) meaning "breastplate" and ἀκαρής (akares) meaning "tiny".
Thoracocare | Etymology
In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle.
Thorax | Structure
The contents of the thorax include the heart and lungs (and the thymus gland); the (major and minor pectoral muscles, trapezius muscles, and neck muscle); and internal structures such as the diaphragm, the esophagus, the trachea, and a part of the sternum known as the xiphoid process). Arteries and veins are also contained – (aorta, superior vena cava, inferior vena cava and the pulmonary artery); bones (the shoulder socket containing the upper part of the humerus, the scapula, sternum, thoracic portion of the spine, collarbone, and the rib cage and floating ribs). External structures are the skin and nipples.
Thorax | Contents
The word "thoracic" means pertaining to the chest, and the thoracic spine comprises the upper portion of the spine that corresponds to the chest area. The upper spine includes twelve vertebrae, and each of the upper nine vertebrae in this section attach to a rib on either side of the spine. Each of the ribs then curves around the side of the body and attaches to the breastbone in front. This forms a sturdy structure (the thoracic cage) that supports and protects the internal organs — the heart, lungs and liver.
Middle back pain | Mechanism
In mammals, the thorax is the region of the body formed by the sternum, the thoracic vertebrae, and the ribs. It extends from the neck to the diaphragm, and does not include the upper limbs. The heart and the lungs reside in the thoracic cavity, as well as many blood vessels. The inner organs are protected by the rib cage and the sternum. Thoracic vertebrae are also distinguished in birds, but not in reptiles.
Thorax | In tetrapods
Another non cardiac cause of chest pain is atelectasis. It is a condition that suffered when a portion of the lung collapses from being airless. When bronchial tubes are blocked, this condition develops and causes patients to feel shortness of breath. The most common cause of atelectasis is when a bronchi that extends from the windpipe is blocked and traps air. The blockage may be caused by something inside the bronchus, such as a plug of mucus, a tumour, or an inhaled foreign object such as a coin, piece of food, or a toy. It is possible for something outside of the bronchus to cause the blockage.
Thorax | Atelectasis
Chest pain can be the result of multiple issues, including respiratory problems, digestive issues, and musculoskeletal complications. The pain can trigger cardiac issues as well. Not all pain that is felt is associated with the heart, but it should not be taken lightly either. Symptoms can be different depending on the cause of the pain. While cardiac issues cause feelings of sudden pressure in the chest or a crushing pain in the back, neck, and arms, pain that is felt due to noncardiac issues gives a burning feeling along the digestive tract or pain when deep breaths are attempted. Different people feel pains differently for the same condition.
Thorax | Pain
In the human body, the region of the thorax between the neck and diaphragm in the front of the body is called the chest. The corresponding area in an animal can also be referred to as the chest. The shape of the chest does not correspond to that part of the thoracic skeleton that encloses the heart and lungs. All the breadth of the shoulders is due to the shoulder girdle, and contains the axillae and the heads of the humeri. In the middle line the suprasternal notch is seen above, while about three fingers' breadth below it a transverse ridge can be felt, which is known as the sternal angle and this marks the junction between the manubrium and body of the sternum.
Thorax | The chest
Only a patient truly knows if the symptoms are mild or serious. Chest pain may be a symptom of myocardial infarctions ('heart attack'). If this condition is present in the body, discomfort will be felt in the chest that is similar to a heavy weight placed on the body. Sweating, shortness of breath, lightheadedness, and irregular heartbeat may also be experienced. If a heart attack occurs, the bulk of the damage is caused during the first six hours, so getting the proper treatment as quickly as possible is important. Some people, especially those who are elderly or have diabetes, may not have typical chest pain but may have many of the other symptoms of a heart attack.
Thorax | Pain
This creates two very typical, isolated slits. The exoskeleton of "Mesonacis" is about 2⅓× as long as wide, measured between the genal angles. The outer ⅓ of the back (or posterior margin) of the headshield (or cephalon) angles forwards from the tip of the pleural spine to the genal angle. The central area of the cephalon (or glabella) and the frontal margin touch or the distance is as long as the margin at most (in jargon: the preglabellar field is short or absent). The thorax has approximately 25 segments, the pleura about 1½× as wide as the axis, excluding the genal spines.
Mesonacis | Description
The thorax is the human chest, or division of an animal's body that lies between the head and the abdomen. Thorax may also refer to:
Thorax (disambiguation) | Introduction
The first thoracic segment (Prothorax), which is the segment closest to the head, is nearly heart-shaped (sub-cordate) and hairless (glabrous). The Prothorax is broad as long, curved like a bow (arcuate) on the side (laterally) from apex to base, but broader in the front (anterior) than in the back part (posterior) where it does not have any curvilinear indentations (not sinuate), but the basal angle is sharp and projects, the outer margin is bent backward (reflexed). On the Prothorax the side groove (lateral sulcus) is narrow and reaches from the front (anterior) angle to the basal pore and is not continued along the basal margin to the basal longitudinal groove (sulcus), the space along the base between the grooves (sulci) and the median longitudinal line is not punctured (impunctate), the front part of the disk which is broadest across the median part is slightly convex and the sides of the rear (posterior) are not depressed or bent backwards (reflexed) on the site (laterally).
Abacetus emeritus | Thorax
The anatomy of the chest can also be described through the use of anatomical landmarks. The nipple in the male is situated in front of the fourth rib or a little below; vertically it lies a little external to a line drawn down from the middle of the clavicle; in the female it is not so constant. A little below it the lower limit of the great pectoral muscle is seen running upward and outward to the axilla; in the female this is obscured by the breast, which extends from the second to the sixth rib vertically and from the edge of the sternum to the mid-axillary line laterally.
Thorax | Anatomical landmarks
The female nipple is surrounded for half an inch by a more or less pigmented disc, the areola. The apex of a normal heart is in the fifth left intercostal space, three and a half inches from the mid-line.
Thorax | Anatomical landmarks
The thorax is the midsection (tagma) of the insect body. It holds the head, legs, wings and abdomen. It is also called mesosoma or cephalothorax in other arthropods. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax. In dragonflies and damselflies the mesothorax and metathorax are fused together to form the synthorax.
Thorax (arthropod anatomy) | Introduction
Another organ in the thorax, traces of which might be present, is the thymus, which might have contributed to a greyish mass of organic origin visible in the neck base; this also contains connective and muscle tissue.
Scipionyx | Liver, heart, spleen and thymus
Clavicles assume an s-shape and lose themselves in shoulders. The lower boundary of thorax assumes a semicircular arch. The rectus abdominis, now reduced in number to two, with the top one incorporated into lower boundary of thorax. There is a small raised plane caused by projection of xiphoid appendage sometimes observable at lower end of sternum. Navel has fold of skin above in most examples. The lower boundary of abdomen assumes shape of semicircle, and the upper edge of torso with two concave curves becomes regular in form. Forearm and hand correctly pronated. Arms sometimes held free from body. Flanks; occasionally at first later regularly, flank and buttock of supporting leg rise in conformity with action.

The word pneumothorax is from the Greek "pneumo-" meaning air and "thorax" meaning chest. Its plural is pneumothoraces.
Pneumothorax | Etymology
The specific epithet was chosen because of the unusually deep and wide chest cavity, from Latin "altus" "deep" and Greek "thorax"/θώραξ, "breastplate, cuirass, corslet". Latin "thorax" was derived from the Greek and had become a usual scientific designation for the chest of the body. The titles of Riggs' 1901 and 1903 articles emphasized that the specimen was the "largest known dinosaur". Riggs followed his 1903 publication with a more detailed description in a monograph in 1904.
Brachiosaurus | Holotype specimen
The rear edge of the breastbone was the deepest point of the thorax. Clavicles or interclavicles were completely absent.
Pterosaur | Shoulder girdle
Detailed physiologic testing proving what percentage of pain in the thoracic spine is caused by disc, facet, rib or muscle are yet to be completed so the answer to the question what is causing the pain often is left unanswered. If thoracic pain presents with weakness or numbness of the legs, bowel or bladder incontinence, and/or falling immediate MRI imaging is indicated.
Middle back pain | Diagnosis
Injuries to the rib cage or sternum is also a common cause of chest pain. It is generally felt when deep breaths are taken or during a cough.
Thorax | Non-cardiac causes of chest pain
"Bathynotus" is derived from the Greek words βαθυς -bathus- meaning "ample"; and νοτος -notos- meaning "back", for the very wide axis of the thorax. The species names are derived as follows.
Bathynotus | Etymology
The thorax consists of 11-17 segments, with the 11th from the front bearing a backward directed spine on the midline.
Redlichia | Description
The articulate midlength part of the body (or thorax) consists of 8 segments. Furrows in the parts outside the axis (or pleural furrows) are diagonal. The pygidium is rounded, and has a long axis with concave, posteriorly parallel sides. Some rings may be faintly defined anteriorly and the axis dissolves in the postaxial field. The areas outside the axis (or pleural fields) are smooth or very faintly ribbed.
Asaphus | Description
The cephalon of "Fallotaspis" is semi-circular in shape, with rounded cheeks that are continuous with long spines that go back to the first half of the thorax. Sutures absent. The thorax has up to 21 segments. The third segment terminating in a long spine that extends back to the fourteenth segment. The tail shield (or pygidium) is very small, about the same length as the two most backward thorax segments combined.
Fallotaspis | Description
The thorax reaches its greatest width at the 6th segment. The frontal part or prothorax consists of 6 segments, with number 5 and 6 fused, and the 6th carrying very large trailing spines. The rear part or opistothorax consists of a variable but extremely large number of segments (up to 97).
Emuellidae | Introduction
The thorax has 17 to 23 segments, gradually diminishing in size. The pleural spines are long and sickle-shaped. The tailshield (or pygidium) is very small and subquadrate in shape.
Nevadella | Description
The thorax consists of six short but wide segments, the outline of which is a continuation of the cheeks. The axis is narrow, less than ⅓× as wide as each of the ribs (or pleurae) to its sides. The tailshield, termed pygidium, is small, approximately wide triangular, with the axis narrow triangular, reaching the border. The axial rings and ribs become less conspicuous further to the back.
Trinucleidae | Description
While the whole arm generally feels painful in TOS, some relief can be seen when ice or heat is intermittently applied to the thoracic region (collar bone, armpit, or shoulder blades).
Thoracic outlet syndrome | Physical measures
The front segment of the thorax (prothorax) carries a pair of legs, and the synthorax carries the middle and rear legs and both pairs of wings. A dark stripe (humeral stripe) often follows the humeral suture, which runs from the base of the front wing towards the base of the middle leg. A paler antehumeral stripe is often found above the humeral stripe.
External morphology of Odonata | Thorax
Thoracentesis , also known as thoracocentesis (from the Greek "thōrax" "chest, thorax"— "thōrakos"—and "kentēsis" "pricking, puncture"), pleural tap, needle thoracostomy, or needle decompression (often used term) is an invasive medical procedure to remove fluid or air from the pleural space for diagnostic or therapeutic purposes. A cannula, or hollow needle, is carefully introduced into the thorax, generally after administration of local anesthesia. The procedure was first performed by Morrill Wyman in 1850 and then described by Henry Ingersoll Bowditch in 1852. The recommended location varies depending upon the source. Some sources recommend the midaxillary line, in the eighth, ninth, or tenth intercostal space.
Thoracentesis | Introduction
Despite this paper little attention was paid to this problem until Carnett developed his simple clinical test. Carnett thought that lower abdominal pain was commonly caused by the lower six thoracic nerves and wanted to be able to distinguish this origin from that arising from the viscera.
Carnett's sign | History
Level with this line the second ribs join the sternum, and when these are found the lower ribs can often be counted. At the lower part of the sternum, where the seventh or last true ribs join it, the ensiform cartilage begins, and above this there is often a depression known as the pit of the stomach.
Thorax | The chest
The thorax has up to 22 segments. The pleural ends are usually rounded. The pygidium is small (micropygous), with an even margin. "A. koninckii" had a modern type of compound eye.
Aulacopleura | Introduction
Its body (or thorax) has 17 segments, with nodes on thorax segments 1 to 14, and a short spine on segment 15 that is at its base about ¼ as wide as the axis. The axis is about ¼ as wide as the thorax. Unlike in the majority of the Olenelloidea, in "Wanneria" thorax segment 3 is not macro-pleural, but equal in size and shape to neighboring segments. Pleural spines slightly arched backwards, extending sideward in the most frontal thorax segments, but gradually more backward and eventually even arching slightly inward in segment 17.
Wanneria | Description
The prothorax rounded on the side, moderately widened in the middle and suddenly narrowed (but not truncated) at a very short distance from the base. Rear angle sharp and projecting, deeply marked (punctured) at base.
Abacetus pumilus | Thorax
The thorax is a series of articulated segments that lie between the cephalon and pygidium. The number of segments varies between 2 and 103 with most species in the 2 to 16 range. Each segment consists of the central axial ring and the outer pleurae, which protected the limbs and gills. The pleurae are sometimes abbreviated or extended to form long spines. Apodemes are bulbous projections on the ventral surface of the exoskeleton to which most leg muscles attached, although some leg muscles attached directly to the exoskeleton. Determining a junction between thorax and pygidium can be difficult and many segment counts suffer from this problem.
Trilobite | Thorax

As a result, pain comes in two phases. The first phase is mediated by the fast-conducting Aδ fibers and the second part due to (Polymodal) C fibers. The pain associated with the Aδ fibers can be associated to an initial extremely sharp pain. The second phase is a more prolonged and slightly less intense feeling of pain as a result of the acute damage. If there is massive or prolonged input to a C fiber, there is a progressive build up in the spinal cord dorsal horn; this phenomenon is similar to tetanus in muscles but is called wind-up. If wind-up occurs there is a probability of increased sensitivity to pain.
Nociceptor | Types and functions
The part of the skeleton that is ‘tucked under’ (the doublure) has no sutures crossing it to form a rostral plate.The thorax has 11 (rarely 10) segments, the side lobes (or pleurae) are furrowed, and the articulating facets distinct.
Phacopina | Description
The scutellum is distinctly visible but rather small. Like in most other Eurybatinae, there is no groove connecting the mesoscutal transverse sutures across the centerline of the mesothorax. The metathorax has a dorsal sclerite shaped like a saddle.
Badisis | Thorax
The date and circumstances of this, however, are very doubtful.
Thorax of Lacedaemonia | Introduction
The lower opening of the thorax is formed by the twelfth thoracic vertebra behind, by the eleventh and twelfth ribs at the sides, and in front by the cartilages of the tenth, ninth, eighth, and seventh ribs, which ascend on either side and form an angle, the infrasternal angle or subcostal angle, into the apex of which the xiphoid process projects. Pregnancy causes the angle to increase from 68° to 103°.
Infrasternal angle | Introduction
The mandibles are elongated, slightly curved near the bases, and narrow. They are separated into distinct base and masticatory areas, with very small uniform teeth populating the whole length of the chewing edge. The thorax forms a slender neck from the prothorax, on which the head is connected, and the remainder of the thorax is narrower in width than the head. The upper surface of the thorax is divided by a distinct constriction between the mesonotum and epinotum. Two small spines rise from the rear edge of the epinotum. The petiole is thin with no teeth on the underside and only a slight thickening into a node on the upper surface.
Electromyrmex | Description
The articulate middle part of the body (or thorax) has three segments. The tailshield (or pygidium has a wide, subconical axis of more than eight rings. The pleural areas to the right and left of the axis lack furrows or are extremely weakly furrowed (on the internal mold only). The border becomes narrower further backwards and usually carries about 8 ventral spines at each side.
Serrodiscus | Description
The articulated middle part of the body (or thorax) has 7-11 segments (9 in "A. wheeleri"), with rounded tips. The tailshield (or pygidium) is about 30% of the body length, is semi-circular in shape, with a wide flat border, and an entire margin.
Asaphiscus | Description
The articulating middle part of the body (or thorax) has 12 segments. The axis is convex, and less than ½× as wide as each of the so-called pleurae to its sides. Segments pointed sideways with a rounded front (a shape called falcate). The tailshield (or pygidium) is about ½× as wide as the cephalon, almost twice as wide as long, excluding the two, widely spaced spines. These are at an angle of approximately 30° with the rest body. The axis in the pygidium is 1¼× longer than wide, with almost parallel sides, almost reaching the rear margin, with 3 or 4 axial rings; 3 sets of interpleural grooves and pleural furrows ending at distance of the margin.
Tricrepicephalus | Description
The CNS does not clearly discern whether the pain is coming from the body wall or from the viscera, but it perceives the pain as coming from somewhere on the body wall, i.e. substernal pain, left arm/hand pain, jaw pain.
Referred pain | Mechanism
First attested in English in 1297, the word "peyn" comes from the Old French "peine", in turn from Latin "poena" meaning "punishment, penalty" (in L.L. also meaning "torment, hardship, suffering") and that from Greek ποινή ("poine"), generally meaning "price paid, penalty, punishment".
Pain | Etymology
The thorax has not been found. The pygidium is convex. Its axis is parallel-sided, and does not reach border furrow. Three pairs of pleural furrows may be discernible. The pygidial border is narrow.
Dicerodiscus | Description
There are several proposed mechanisms for referred pain. Currently there is no definitive consensus regarding which is correct. The cardiac general visceral sensory pain fibers follow the sympathetics back to the spinal cord and have their cell bodies located in thoracic dorsal root ganglia 1-4(5). As a general rule, in the thorax and abdomen, general visceral afferent (GVA) pain fibers follow sympathetic fibers back to the same spinal cord segments that gave rise to the preganglionic sympathetic fibers. The central nervous system (CNS) perceives pain from the heart as coming from the somatic portion of the body supplied by the thoracic spinal cord segments 1-4(5).
Referred pain | Mechanism
Greek: hemi (half) + para (beside) + aisthesis (sensation)
Hemiparesthesia | Etymology
The furrows that separate border, eye ridges, glabella and its lobes are distinct (unlike in the Biceratopsinae). The area outside of the axis (or pleural lobes) of the third segment of the thorax are greatly enlarged, and carrying large trailing spines. These extend further back than the rest of the body except for the axial spine that is carried by the most backward (15th) prothorax segment. The pleural lobes of the 1st, 2nd, 4th and 5th are consequently triangular in shape and edge forward and backward respectively, and do not carry spines. Prothorax segments further back carry slender spines that angle backwards.
Bristolia | Description
Some diagnostic procedures, such as lumbar puncture (see post-dural-puncture headache), venipuncture, paracentesis, and thoracentesis can be painful.
Cancer pain | Diagnostic procedures
It lacks the long axial spine where prothorax ends. The portion of the thorax where the pleural lobes are reduced (or opisthothorax) consist of at least 23 segments.
Nephrolenellus | Description
The elytra are convex, broader than the thorax, with a prominent humeral callus, and pointed at the apex ; on each elytron are nine rows of large oblong punctures, the intervals scarcely raised ; the extreme apex is mucronate. A sutural vitta including the scutellum, a broadish fascia behind the shoulder and not reaching the suture, and a narrower rather curved fascia behind the middle and extending to the suture, are densely clothed with golden scales. The metasternum is similarly clothed. The legs are sparingly punctured, each puncture with a short seta. "
Rhinoscapha maclayi | Description
The prothorax is the simplest and smallest of the three segments while the mesothorax is the most developed. Between the head and thorax is the membranous neck or "cervix". It comprises a pair of lateral cervical sclerites and is composed of both cephalic and thoracic elements. Between the head and the thorax is a tufted scale called the pronotum. On either side is a shield-like scale called a scapula. In the Noctuoidea, the metathorax is modified with a pair of tympanal organs.
External morphology of Lepidoptera | Thorax
The sudden impact on the thorax causes an increase in intrathoracic pressure. In order for traumatic asphyxia to occur, a Valsalva maneuver is required when the traumatic force is applied. Exhalation against the closed glottis along with the traumatic event causes air that cannot escape from the thoracic cavity. Instead, the air causes increased venous back-pressure, which is transferred back to the heart through the right atrium, to the superior vena cava and to the head and neck veins and capillaries.
Traumatic asphyxia | Pathophysiology
Ventrally, a large plate has been interpreted as a hypostome. The head shield overlaps a tapering series of 12–17 trunk tergites, which lead into a set of limb-bearing segments comprising the thorax. The limbs are simple in form, consisting of a smooth oval exopod and a stout, annulated endopod. There is no one-to-one correspondence between the thoracic tergites and the limbs, but, rather, there appear to be two or three limbs per tergite. Behind the thorax is a narrower abdominal region, consisting of 14 tergites, that bears no appendages. The abdomen is terminated by a telson-like spine.

The thorax constitutes a large portion of the insect's body. As in all insects, it is composed of three segments: the prothorax, mesothorax, and metathorax. Each section "contains one pair of legs, however, the wings are found only on the mesothoracic and metathoracic segments."
Idolomantis diabolica | Thorax
Almost the entire body of "T.grandis" is covered with spines and tubercles of varying sizes. The pygidium is large and shield-like with four pairs of slightly curved barbed spines on the sides. The thorax consists of around 11 segments. The cephalon is characterized by its swollen front portion and longitudinal furrows that delinates a pair of swellings that located in line with the eyes. The hypostome is almost flat and kidney-shaped and has a poorly defined central body.
Terataspis | Description
Some zoologists consider the thorax to consist of the two regions with appendages, and the abdomen the region without appendages. Others believe the region of fused segments to be part of the abdomen. For clarity, this article uses "thorax" to mean the two body regions with limbs.
Triops longicaudatus | Structure
The rhachis is about ⅓ of the pygidial width anteriorly, tapering evenly backwards. There is no pygidial border. There may be small spines extending from the frontal corners of the pygidium.
Thoracocare | Description
Neighbouring pleurae are displaced because of the large pleurae of the 3rd segment. The back thorax (or opistothorax) consists of about 10 progressively smaller segments with insignificant pleurae. Tail shield (or pygidium) not known.
Biceratops | Description
The body, or gladiolus, is the longest part. It is flat and considered to have only a front and back surface. It is flat on the front, directed upward and forward, and marked by three transverse ridges which cross the bone opposite the third, fourth, and fifth articular depressions. The pectoralis major attaches to it on either side. At the junction of the third and fourth parts of the body is occasionally seen an orifice, the sternal foramen, of varying size and form. The posterior surface, slightly concave, is also marked by three transverse lines, less distinct, however, than those in front; from its lower part, on either side, the transversus thoracis takes origin.
Sternum | Body
Other, less common causes of thoracic back pain include a spinal disc herniation which often may have radicular pain (wrapping around the ribs associated with numbness and burning pain), spinal tumors and rib fractures may mimic thoracic pain/radicular pain. Other possible sources of referral pain into the thoracic region include visceral organs like: lungs, gallbladder, stomach, liver duodenum, pleura and cardiac.
Middle back pain | Causes
The iliocostalis thoracis (musculus accessorius; iliocostalis thoracis) arises by flattened tendons from the upper borders of the angles of the lower six ribs medial to the tendons of insertion of the iliocostalis lumborum; these become muscular, and are inserted into the upper borders of the angles of the upper six ribs and into the back of the transverse process of the seventh cervical vertebra.
Iliocostalis | Iliocostalis thoracis
It is also possible to classify TOS by the location of the obstruction: Some people are born with an extra incomplete and very small rib above their first rib, which protrudes out into the superior thoracic outlet space. This rudimentary rib causes fibrous changes around the brachial plexus nerves, inducing compression and causing the symptoms and signs of TOS. This is called a "cervical rib" because of its attachment to C-7 (the seventh cervical vertebra), and its surgical removal is almost always recommended. The symptoms of TOS can first appear in the early teen years as a child is becoming more athletic.

The genal spine is short and stout. The articulate middle part of the body (or thorax) has 15 to 18 segments with long, sickle-shaped spines. The inner part of the ribs is about as wide as the axis. The tailshield (or pygidium) is longer than wide, slightly hexagonal, with a long, flat posterior area. The rear margin of the pygidium is truncate or indented. The pygidial axis is short, with 1 axial ring. The surface is smooth.
Anabaraspis | Description
The muscle fibres of the diaphragm emerge from many surrounding structures. At the front, fibres insert into the xiphoid process and along the costal margin. Laterally, muscle fibers insert into ribs 6–12. In the back, muscle fibres insert into the vertebra at T12 and two appendages, the right and left crus, descend and insert into the lumbar vertebrae. Right crus arises from L1-L3 their intervertebral discs. Left crus from L1, L2 their intervertebral discs. There are two lumbocostal arches, a medial and a lateral, on either side.

The free cheeks curve strongly downwards and have prominent borders, particularly to the side and the back, and these bear long tube- or blade-like genal spines. The articulating middle part of the body (or thorax) consists of 9 or 10 segments. The axis is extremely convex and the side-lobes (or pleurae) are narrow. The tailshield (or pygidium) is convex and its axis is prominent and has 2-4 rings. The most backward piece may bear a long spine. The seam of the exoskeleton (or doublure) is narrow.
Telephinidae | Description
Just like with a heart attack, not all chest pain is suffered because of a condition involving the heart. Chest wall pain can be experienced after an increase in activity. Persons who add exercise to their daily routine generally feel this type of pain at the beginning. It is important to monitor the pain to ensure that it is not a sign of something more serious. Pain can also be experienced in persons who have an upper respiratory infection. This virus is also accompanied by a fever and cough. Shingles is another viral infection that can give symptoms of chest or rib pain before a rash develops.
Thorax | Non-cardiac causes of chest pain
The condition affects all major structures within the thorax and abdomen. Generally, the organs are simply transposed through the sagittal plane. The heart is located on the right side of the thorax, the stomach and spleen on the right side of the abdomen and the liver and gall bladder on the left side. The heart's normal right atrium occurs on the left, and the left atrium is on the right. The lung anatomy is reversed and the left lung has three lobes while the right lung has two lobes. The intestines and other internal structures are also reversed from the normal, and the blood vessels, nerves, and lymphatics are also transposed.

Underside: as in the typical form. Antenna, head, thorax and abdomen similar.
Curetis thetis | Male
The breastbone is somewhat wide, and was formed by fused paired "sterna". At its rear, a row of belly ribs or gastralia was present, covering the entire belly. To the front of the breastbone, a long point called the "cristospina", jutted obliquely upwards, and the rear edge of the breastbone was the deepest point of the thorax. The absence of clavicles or interclavicles had made paleontologists wonder if pterosaurs evolved in different ways than other archosaurs.
Ornithocheiromorpha | Shoulder girdle
Different types of diseases or conditions that affect the chest include pleurisy, flail chest, atelectasis, and the most common condition, chest pain. These conditions can be hereditary or caused by birth defects or trauma. Any condition that lowers the ability to either breathe deeply or to cough is considered a chest disease or condition.
Thorax | Clinical significance
The articulating middle part of the body (or thorax) has 13 segments. The axis is convex, and less than ½× as wide as each of the so-called pleurae to its sides. Segments pointed sideways with a rounded front (a shape called falcate). The tailshield (or pygidium) is about ½× as wide as the cephalon, almost twice as wide as long, excluding the two flat, shark tooth shaped, widely spaced spines. The axis in the pygidium is 1¼× longer than wide, with almost parallel sides, almost reaching the rear margin, with 3 or 4 axial rings; 3 sets of interpleural grooves and pleural furrows ending at distance of the margin.
Meteoraspis | Description
In the thoracic region they are present between the transverse processes of the lower three thoracic vertebrae, and between the transverse processes of the last thoracic and the first lumbar. These are called the " thoracic intertransversarii" and are supplied by the posterior rami of the spinal nerves.
Intertransversarii | Thoracic
Rembrandt's image is a fiction; in a typical anatomy lesson, the surgeon would begin by opening the chest cavity and thorax because the internal organs there decay most rapidly.
The Anatomy Lesson of Dr. Nicolaes Tulp | Background
The name refers to the brown arch of scales on the back of the thorax and is derived from Latin archi (meaning arch) and medias (meaning middle).
Sorolopha archimedias | Etymology
This pattern is repeated with all thorax segments. Antennae are not known. Dorsal eyes are absent. The thorax segments are each about along the axis. The tail shield is dominated by a pair of large segmental marginal spines, reminiscent of large (or macropleural) spines in the thorax and of pygidial spines of certain trilobites. The one node it carries is larger and more sharply defined than the nodes on the segments. The frontal border of the tail shield is convex and curves laterally into the large spines which extend postero-laterally, constituting half the total body length. The back margin of the spines is concave and merges into a second pair of short, broad, triangular spines.
Aaveqaspis | Description
Antennae, head, thorax and abdomen much as in the male.
Prosotas nora | Description
It was transparent, however, & I saw, through it, that the Bed stead was instantly surrounded by the 7 men & my nurse. I refused to be held; but when, Bright through the cambric, I saw the glitter of polished Steel – I closed my Eyes. I would not trust to convulsive fear the sight of the terrible incision. Yet – when the dreadful steel was plunged into the breast – cutting through veins – arteries – flesh – nerves – I needed no injunctions not to restrain my cries. I began a scream that lasted unintermittingly during the whole time of the incision – & I almost marvel that it rings not in my Ears still? so excruciating was the agony.

There is a pain — so utter — | Text
The side lobes of the thorax (or pleurae, singular pleura) have rounded ends. The pygidium is well rounded, semicircular or shorter, with an entire margin, and without lateral and posterior projections. In many Phacopidae, where the facial sutures are apparently continuous and well developed, they were evidently nonfunctional in ecdysis, since no separate free cheeks can be found.
Viaphacops | Description
The anterior thorax consists of eleven segments, each bearing a pair of appendages, called thoracopods or pereiopods. None of the thoracopods are modified into maxillipeds for feeding. The posterior thorax consists of 16–25 segments, incompletely separated to form "rings". Each ring may consist of as many as six fused segments and bear up to six pairs of appendages (there are 54–66 limbs altogether). Most of the thoracic appendages resemble each other, but the first eleven pairs are best developed. There is a slight tendency to regional specialization and the first pair of legs is unlike the rest. It is an elongated, cheliped-like structure with a sensory function, while all the other appendages aid in feeding, respiration, and locomotion.
Triops longicaudatus | Thorax
If pygidial spines are lacking, the margin is gradually rounded. The thorax has 12 segments.
Dikelocephalus | Introduction
Head, black, small, and triangular, having three tubercles issuing from it, of which the anterior is pointed, the others blunt. Thorax black, which is the general colour of the insect, rounded, smooth, and margined, having an impression in front, with a short tubercle situated on it near the edge; from whence runs a hollow groove or channel to the posterior margin. Scutellum small. Elytra shining, margined and furrowed. Abdomen smooth and shining, without hair. Tibiae furnished with spines, as are the first joints of the middle and posterior tarsi. Length 2 inches.
Phileurus didymus | Description
Reduced movement of the ribcage during breathing, reduced breath sounds on the affected side(s), and a dull feeling when the chest is pressed are common signs observed during examination for fibrothorax. Sharp chest pain with deep breaths or coughing may be seen in some cases. Severe cases of fibrothorax can lead to respiratory failure due to inadequate ventilation and cause abnormally high levels of carbon dioxide in the bloodstream.
Fibrothorax | Signs
They are made up of thousands of little receptors called ommatidia. The antennae are covered with many chemical receptors and act as sensory organs. "N. tomentosus" has a mandible for chewing its food. The thorax is the center of movement. It is separated into three different regions: the prothorax, the mesothorax, and the metathorax. It is heavily scleratized which provides extra support and acts as an anchor for moving parts. It is also divided into three different sections. The notum is the top most or dorsal area, the sternum is the lower or ventral side, and the pleuron is the sides where the legs are attached.
Nicrophorus tomentosus | Anatomy
In terms of anatomy, the body is divided into regions. In the front, the trunk is referred to as the "thorax" and "abdomen". The back as a general area is the dorsum or dorsal area, and the lower back is the lumbus or lumbar region. The shoulder blades are the scapular area and the breastbone is the sternal region. The abdominal area is the region between the chest and the pelvis. The breast is also called the mammary region, the armpit as the axilla and axillary, and the navel as the umbilicus and umbilical. The pelvis is the lower torso, between the abdomen and the thighs.
Anatomical terminology | Regions
"Thoracocare" is a very small to minute trilobite (1.7 – 3.6 mm long in adulthood), with an elliptical body outline. The headshield (or cephalon) and tailshield (or pygidium) are of approximately same size (or isopygous) with 2 thoracic segments between them. The central raised area of the cephalon (or glabella) is broad, subrectangular, tapering slightly to the back in larger specimens and touching the frontal border, and without transverse furrows. Fixed cheeks are subtriangular. Free cheeks are rarely present. Dorsal sutures are proparian. The pygidium is subcircular, about 1⅔× as wide as long. The segmentation of the pygidial axis (or rhachis) and pleura is indiscernible or very weak.
