The abdomen is sometimes highly modified. In Apocrita (bees, ants and wasps), the first segment of the abdomen is fused to the thorax and is called the propodeum. In ants the second segment forms the narrow petiole. Some ants have an additional postpetiole segment, and the remaining segments form the bulbous gaster. The petiole and gaster (abdominal segments 2 and onward) are collectively called the metasoma.

It starts off with circular abdominal massage to aid digestion by warming and supporting spleen yang, using the entire upper torso to move the hands. The arms are then poised to open and stretch the armpit activating the spleen's close relationship with Heart and Liver (Heart is the 'mother' of spleen and liver stores xue) by stretching the flanks. The palms are empty to open PC-8 as the hip is raised to shift the leg forward while keeping the knee straight. The swinging torso and heavy step activates kidney yang to supports spleen yang in heating and 'cooking' food.

The emphasis of this exercise is grasping and stretching. By reaching up to bring down Heaven and reaching down to draw up Earth grasping is encouraged; which relates to sinews and therefore the liver. Rolling through the spine stimulates both yin and yang of ren mai and du mai channels activating the microcosmic orbit. This is then completed with a slow 'stalking' forward bend and sudden shout (release of anger) as the Tiger catches its prey with vigor while standing on one leg, to stretch the sinews while activating the jing-well points at the tips of the fingers, opening PC-8 and incorporating another important Wood trait – balance.

In arthropods the abdomen is built up of a series of upper plates known as tergites and lower plates known as sternites, the whole being held together by a tough yet stretchable membrane. The abdomen contains the insect's digestive tract and reproductive organs, it consists of eleven segments in most orders of insects though the eleventh segment is absent in the adult of most higher orders. The number of these segments does vary from species to species with the number of segments visible reduced to only seven in the common honeybee. In the Collembola (Springtails) the abdomen has only six segments.

Eight, you can sit down on a bed with your legs straight and you will lie back and come back up without using your hands. Ninth, you will place your arms on the side of a chair and with your legs backwards you will push down until your abdominal touches the chair. Tenth, you will lie down with your feet straight and raise your legs up to a right angle and then back down. For a better visual understanding, all these exercises were obtained from an Abdominal Exercise Journal.

Jumping action achieved by balancing on third to last pair of legs while turning the abdomen under the body so the end of the uropods and telson press on to the ground. The last two pairs of legs are held parallel to but not touching the ground. When the abdomen is suddenly straightened out the animal is propelled into the air. On landing the abdominal limbs and last two pairs of legs are used as shock absorbers to cushion the impact.
Bellorchestia quoyana | Description
There are multiple ways to work on our abdominals but here are ten abdominal exercises you can do that are effective. One type of exercise you can do is to lie on your back and put your feet at a 45° angle and move your legs as if you were riding a bicycle. Second, you can lay down with your hands on the side of your body and position a book on your stomach and raise your stomach up and down. Third, you can lay down and position your feet at a 45° angle and lift them up straight and bend them back down to the 45° angle then repeat.

With the first exercise, suddenly lifting the hands with hook palms up towards the chest, the shoulders towards the ears and balancing on the toes with the monkey looking to the side, squeezes the heart and pumps xue as you release down again. The second part calms Shen by clearing the mind (moving the branch) to grasp the peach (fruit of heaven) with the thumb inside of the palm to hold the Hun within. Grasping in this exercise relates to the liver's ability to hold and store xue, while the lifting of the back heel activates the Kidneys also supporting the Heart.

The body of "P. homarus" can reach up to in total length, or a carapace length of , but the average is around . There is variation in the colouration, which parallels other morphological differences; most animals are dark green and have only very small squamae in the grooves of the abdominal tergites. Other animals are red, and have much more prominent sculpturation in the grooves on the abdominal tergites. The green form is known as the ' form, and the red form as the ' form.
Panulirus homarus | Description
The final stretch upwards on one leg stretches the flanks and therefore the liver and gall bladder channels to balance with the Lungs. The lungs are said to be 'spoilt' being the last organ to start working just after birth and are therefore fragile and sensitive to change, explaining why gentle exercise is preferred.

The "Five Animal play" (五禽戲, Wu Qin Xi) are a set of qigong exercises developed during the Han dynasty (202 BC – 220 AD). Some claim the author of this Qi Gong sequence to be Hua Tuo, however Yang Jwing-Ming suggests it was the Taoist Master Jiun Chiam and Huatuo merely perfected its application and passed it onto gifted disciples including Wu Pu, Fan E, and Li Dangzhi. The five animals in the exercises are the tiger, deer, bear, monkey and crane. According to TCM theory of Wu Xing (Five Elements), each animal has two exercises corresponding to the yin and yang internal organs (Zang/Fu).

Although the precise shape and size of the stomach varies widely among different vertebrates, the relative positions of the oesophageal and duodenal openings remain relatively constant. As a result, the organ always curves somewhat to the left before curving back to meet the pyloric sphincter. However, lampreys, hagfishes, chimaeras, lungfishes, and some teleost fish have no stomach at all, with the oesophagus opening directly into the anus. These animals all consume diets that require little storage of food, no predigestion with gastric juices, or both. The gastric lining is usually divided into two regions, an anterior portion lined by fundic glands and a posterior portion lined with pyloric glands.

Being key elements of spinal support, and contributors to good posture, it is important to properly exercise the abdominal muscles together with the back muscles because when these are weak or overly tight they can suffer painful spasms and injuries. When properly exercised, abdominal muscles contribute to improved posture and balance, reduce the likelihood of back pain episodes, reduce the severity of back pain, protect against injury by responding efficiently to stresses, help avoid some back surgeries, and help with the healing of back problems, or after spine surgery. When strengthened, the abdominal muscles provide flexibility as well. The abdominal muscles can be worked by practicing disciplines of general body strength such as Pilates, yoga, T'ai chi, and jogging.
Abdomen | Exercise
Abdominal exercises are type of strength exercise those that affect the abdominal muscles (colloquially known as the stomach muscles or "abs").
Abdominal exercise | Introduction
Although the technique is mainly associated with the tiger, dragon, snake, crane and leopard, many other animal styles have been developed:
Five Animals | List of animal styles
Fourth, you can stand straight with both of your arms opened and straight and bend down to the left then to the right by using one hand at a time. Fifth, you can stand up and position your hands on your hips and rotate your body to the right then the left. Sixth, you can stand up straight and position your hands on your hips and rotate your body from right to left and vice versa while bending forward and backwards. Seventh, you can sit on top of your legs in a bed and bend your chest forward until it touches the bed then come back up to your normal position.

The fourth abdominal segment bears an organ known as a "dens", and at the tip of this is a structure known as a "mucro". This species has mucros with smooth outer edges and saw-edged inner edges. In females, the appendage on the fifth abdominal segment is unforked.
Allacma fusca | Description
The third animal is Bear. It relates to the earth element, the season of late summer and therefore the spleen and stomach. The spleens emotion is worry and is the central organ in the production of gu qi; from the food and drink, we ingest. The spleen's transformation and transportation of gu qi are paramount in the process of digestion which is the basis for the formation of qi and xue. The spleen is where the intellect (yi) is said to reside and is responsible for applied thinking and the generating of ideas, memorizing and concentration. This animal is cumbersome and its awkward traits are expressed in each movement.
Five Animals | Bear
The front margin of the opisthosoma tucks into a corresponding fold at the back of the carapace. The advantages of this unusual system are not well understood, and since the genital opening is located on the pedicel (another rather unusual feature) the animals have to 'unlock' themselves in order to mate. The abdomen is divided dorsally into a series of large plates or tergites, each of which is subdivided into a median and lateral plate.
Ricinulei | Body
The shoulders are raised and squeezed into the neck to squeeze the heart and pump xue while the arms are brought up to mimic a beak and the tailbone is thrust out. The arms are brought back along with one leg to mimic gliding. The second part of the exercise regulates the ascending (liver – xue) and descending (lungs – qi) function of qi in the Lungs. The ultimate yin and yang expressed by breathing in (kidneys) and breathing out (lungs) connects these two organs to regulate xue and assist the heart. The rhythm created by the up and down movement of the body, the opening and closing of the arms (lung and large intestine channels) and the in and out breath helps us adapt to the rhythmical changes of the seasons.
Five Animals | Crane
The material becomes tightly stretched and the intestines may "accordion up" on themselves or be lacerated by it. This is especially common in cats who may enjoy playing with a ball of string or yarn. Sometimes the linear foreign body anchors in the mouth by catching under the tongue. Pantyhose is a common linear foreign body in dogs.

The abdomen has seven segments in both sexes with the male abdomen being more narrowwith the segments being broader than longer. The legs are longest in the front and get progressively shorter towards the back. It has three pairs of walking legs, a pair of swimming legs in the back, and a pair of claws at the front called chelipeds. The walking legs are long and slender with the back of the legs covered in a longitudinal row of short hooked bristles including long straight bristles. The pincers are orange or red with white tips, and the legs have brown hairs.
Notomithrax ursus | Species description
Shasangasana (शसांगासना) or "Rabbit Pose", practised in Bikram Yoga, has the tailbone lifted until the thighs are vertical and the head and arms pointing back towards the feet, creating an intense flexion of the spine.
Balasana | Variations
The colour of abdomen is the same as the rest of the body, and are either bi-punctate or tri-punctate at the base.
Porcellio formosus | Description
A jackknife is an abdominal exercise. This exercise is also known as a "V-Up". Jackknife exercises are designed to strengthen the upper and lower abdominal muscles, particularly the transversus abdominis muscle. There are a number of variations of jackknife exercises that allow people of different ages and ability to work their abdominal muscles. This exercise can be modified by using an exercise ball. The jackknife can be done by lying flat on your back with your arms extended overhead and your feet raised slightly above the floor. The jackknife is completed by slowly bringing your straight arms toward your hips, and lifting your upper torso off the floor.
Jackknife (exercise) | Introduction
These include muscles, which enable locomotion, and nerve tissues, which transmit signals and coordinate the body. Typically, there is also an internal digestive chamber with either one opening (in Ctenophora, Cnidaria, and flatworms) or two openings (in most bilaterians).
Animal | Structure
This animal usually grows to in length, though individuals as long as have been reported. Its nervous system consists of a nerve net with no defined brain or ganglia. The nerve net is found on the basal (away from the animal's surface) side of the skin. This animal lacks a coelom. It also lacks an anus, excreting waste through the same opening as it intakes food. Thus, the digestive organ is sac-like. The opening is on the belly of the animal, near the front. The animal is simultaneously hermaphroditic. A furrow runs along the circumference of the body in the middle of the animal.
Xenoturbella bocki | Description
The abdomen (colloquially called the stomach," belly, tummy or midriff") is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the trunk. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between L5 and S1) to the pubic symphysis and is the edge of the pelvic inlet.
Abdomen | Introduction
This process is known as polyphyodonty and, amongst other mammals, only occurs in elephants and manatees.
Kangaroo | Diet
This muscle is the innermost abdominal muscle. Its origin is the second sheet of the lumbodorsal fascia and the pelvic girdle and its insertion is the linea alba. Its action is the compression of the abdomen.
Cat anatomy | Transversus abdominis
The shape of the head often resembles a giraffe, causing confusion between the two signs. The general body shape is that of a canine.
Set animal | Physical characteristics
Most males moved toward the female in a zigzag path (with a sideways motion as much as 1 cm), with pauses during which the abdomen was straightened and then re-twisted. However some males proceeded in a straight path. When the male reached about 1 cm from the female he straightened his abdomen and stretched his front legs forward, eventually touching the female, raising and lowering his legs two or three times. If she was receptive the male then see-sawed his front legs over her several times and then mounted and twisted her abdomen before inserting one palp into her epigynum, repeating with a second palp on the other side.
Hentzia | Behavior
Abdominal exercises can also be performed with the help of some machines and the captain's chair is one of the most popular machines used in gyms and health clubs. Other machines are the Ab Roller, the Ab Rocket Twister, the Chin-up bar in conjunction with Ab Straps and the Torso Track. The exercise ball is also a tool that helps strengthen the abs. It may be more effective than the crunches on the floor because the abs do more work as the legs are not involved in the exercise. With respect to the Ab-Slide, the study performed by Bird et al.
Abdominal exercise | Gadgets
When looking at the sides of the face, one can see that "the distance from the cheeks to the temples is disproportionately large." The figure is extensively modeled creating harsh contour lines especially on the knees and abdomen. The muscles are "rendered by grooves, with a decorative intent that is carried to the point of excess and stylisation." The inguinal ligament which creates a triangle shape in the lower abdomen is strongly modeled. Grooves on the abdomen suggest two more abdominal muscles than what is anatomically correct.

Baiami brockmani | Description
These animals swim horizontally using muscular contractions as well as the beating of the comb rows. The oral edge leads. They eat small crustaceans.
Venus girdle | Ecology
The incision leaves a mark that is an inverted Y inside of a circle. After piercing the skin and injecting anticoagulants (hirudin) and anaesthetics, they suck out blood, consuming up to ten times their body weight in a single meal. In some species of Bryozoa, the first part of the stomach forms a muscular gizzard lined with chitinous teeth that crush armoured prey such as diatoms. Wave-like peristaltic contractions then move the food through the stomach for digestion.
Tooth | Invertebrates
Unusually, however, palpigrades use their pedipalps for locomotion, so that the animal appears to be walking on five pairs of legs. Some palpigrades have three pairs of abdominal lung-sacs, although these are not true book lungs as there is no trace of the characteristic leaflike lamellae which defines book lungs. However, many species have no respiratory organs at all and breathe directly through the cuticle.
Palpigradi | Description
Animals who exhibit suspensory behaviour have similar mechanisms to perform this action and often involve many different parts of their body like the trunk, shoulders and many other features of their upper body. Typically, these animals have an overall dorso-ventral flattening, a shortened lumbar region and a mediolateral expansion of the rib cage causing the scapula to be repositioned dorsally and humeral articulation to be oriented more cranially than the usual lateral placement shown in quadrupedal animals. The scapula is also longer, giving these animals a particular arm and shoulder shape. Combined, these morphologies allow for the infraspinatus muscle to be repositioned creating more resistance to trans articular tensile stress for suspending below a branch.
Suspensory behavior | In primates and sloths
The bicycle targets the rectus abdominals and the obliques. Also, the rectus abdominals can be worked out with the basic crunch, the vertical crunch, the reverse crunch, and the full vertical crunch, and when at a low enough body fat percentage (10-12% for males, 15-18% for females) the individual parts of the muscle become visible; many refer to this visible separation as a six pack. By exercising the internal and external obliques the stomach can be flattened while the waist line can be reduced. The long arm crunch, in which arms are straightened behind you, adds a longer lever to the move and emphasizes the upper part of the abs.
Abdominal exercise | Bicycle crunch
The remaining animals, the great majority—comprising some 29 phyla and over a million species—form a clade, the Bilateria. The body is triploblastic, with three well-developed germ layers, and their tissues form distinct organs. The digestive chamber has two openings, a mouth and an anus, and there is an internal body cavity, a coelom or pseudocoelom. Animals with this bilaterally symmetric body plan and a tendency to move in one direction have a head end (anterior) and a tail end (posterior) as well as a back (dorsal) and a belly (ventral); therefore they also have a left side and a right side.
Animal | Bilaterian animals
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
Both sexes, when threatened, adopt a threat pose, standing on the front and middle legs, pointing their abdomen up or to the side in a sort of "scorpion" pose. They fold back their legs to defend themselves if anything comes in contact with their abdomen; the pincer movement with the sharp spines on the rear legs can puncture human skin. Adults make clicking sounds and can release a defensive odor reminiscent of toffee. Males may attempt to startle predators by flashing their wings open.
Extatosoma tiaratum | Threat behaviour
Paralyzed prey are carried in the females' mandibles, which are somewhat elongated and tend to have prominent teeth, often with species-specific shapes. The abdominal segments are also constricted very strongly at the junctures, giving the abdomen a somewhat corrugated, accordion-like appearance.
Cerceris | Introduction
A method of developing long-term daily endurance in the muscles is to tie a string around the waist at the bellybutton level. The string is tied at 3/4 of one's maximum vacuum point. The string should be tight, but not noticeably cutting into the skin. When the transverse abdominis relaxes, the abdominal wall (belly) expands and the string will tighten for immediate feedback, reminding the user to contract the TA.
Vacuum exercise | String method
The abdomen is long and sports a robust ovipositor that has dense annulations along its length. The ovipositor is approximately long, thick, sporting short, stiff, sensory setae along its length and a club-shaped gonostyli.
Alavaraphidia | Description
The living animal has a general orange color. The whole dorsum has brown dots except the tips or apex of the lateral appendages, which are pale yellow. The dorsum has a white diamond shaped spot that runs from the behind of the rhinophores to the tail (just behind the branchial leaves). The end of the foot is acute and has a similar color to the appendage apices. Two types of appendages are observed. The first type of appendages are longer and wider and are positioned at the margin of the sides of the animal. These appendages have apical ramifications that are rounded at the base with a long, thin and sharp prolongation.
Kaloplocamus maru | Description
The abdomen ends in a telson and a pair of long, thin, multi-articulate caudal rami. The form of the telson varies between the two genera: in "Lepidurus", a rounded projection extends between the caudal rami, while in "Triops" there is no such projection.
Notostraca | Description
The process of copulation for "T. helluo" consists of a series of interactions between the male palp and the female epigynum. First, the male will mount the female such that they are facing opposite from each other. The underside of the cephalothorax is positioned against the dorsal section of the female’s abdomen. The male then will signal the female to rotate the abdomen by touching the anterior of the female abdomen. After this, the male will then use his palp to engage with the female’s abdomen and epigynum. The right and left palps will interact with the right and left sides of the epigynum.
Tigrosa helluo | Copulation
Body is narrow and elongate. Rhinophores are smooth with tight rhinophoral sheaths. Cerata are with rounded tubercles; apical tubercles are much larger than the rest. Cerata are spaced out along the dorsum. Background color is translucent gray with a series of opaque white spots on the dorsum. Cerata are with cream or white extensions of the digestive gland. The body size is up to 4 mm.
Doto wildei | Description
The standing practices involve nine static strengthening postures specific to a given animal. Each posture requires precise body alignment and distinct isometric pressures necessitating full body exertion to maintain properly. These postures are undertaken to develop and check the structure of every part of the body.

There is no carapace, but each of the eleven free segments bears a pair of phyllopodia, which have a series of bristles pointing along the animal's midline. The abdomen consists of seven segments without appendages, and a slender telson which bears a pair of caudal rami.
Chirocephalus diaphanus | Description
The muscle is common in lower primates but has been lost as a discrete muscle in apes, although it has reoccurred in chimpanzees.
Epitrochleoanconeus muscle | Other animals
The clear part of abdomen is now of a vivid red, and the black stripes remain. Subadults have carapace and legs brown with sparse pinkish long hairs. Dorsum of abdomen is still reddish, but the black stripes begin to fade. Adult female is completely brown with long pinkish setae on legs, carapace and chelicerae. Abdominal pattern is lacking or very inconspicuous. Adult male carapace, chelicerae and legs are brown and covered by pinkish setae, except for the tarsi and a stripe on metatarsi that are black. Abdomen is a vivid orange-red, there is no vestige of any pattern.
Pachistopelma rufonigrum | Characteristic features
When the animal's mouth is closed, it holds a thick flap of skin between its jaws, behind its canines, and the animal uses the muscles of its lower back and forequarters to pull back, tearing the flap clear of the body. This large gash, once opened, leaves intestines uncovered and arteries and veins torn. The bleeding animal would die within minutes, and the shock of repeated bites, tearing innards from the body, could speed up the process. This method allows social machairodonts to inflict large wounds on prey animals. Massive blood loss would ensue, and though bloody, the social group would be able to fend off almost any animal attracted to the area.
Machairodontinae | "Belly shearing"
The body is segmented with eleven segments clearly visible: the three thoracic and eight abdominal segments. The body of pupa is broadly elongate with the pronotum flaring towards the mesonotum and the abdomen tapering to the terminal abdominal tergite. There are no spines anywhere on the body.

In the Macrodasyida, there are additional adhesive glands at the anterior end and on the sides of the body. The body wall consists of a cuticle, an epidermis and longitudinal and circular bands of muscle fibres. In some primitive species, each epidermal cell has a single cilium, a feature shared only by the gnathostomulans. The whole ventral surface of the animal may be ciliated or the cilia may be arranged in rows, patches or transverse bands. The cuticle is locally thickened in some gastrotrichs and forms scales, hooks and spines. There is no coelom (body cavity) and the interior of the animal is filled with poorly differentiated connective tissue.
Gastrotrich | Anatomy
These muscles are limited to about twelve muscles running longitudinally from the siphonal plate, a slightly depressed area between the siphons. The muscles extend for about a quarter of the length of the zooid and their function is to enable the animal to contract and protect its siphons. The only other musculature is the circular sphincter muscles which control the size of the siphons. The siphons each have six or more pointed lobes and the opening into the pharynx is surrounded by ten large and ten small tentacles, designed to prevent the entry of particle too large for the animal to cope with.
Perophora viridis | Description
The abdomen of species like "Camponotus inflatus" consists of hard dorsal sclerites (stiff plates) connected by a softer, more flexible arthrodial membrane. When the abdomen is empty, the arthrodial membrane is folded and the sclerites overlap, but when the abdomen fills the arthrodial membrane becomes fully stretched, leaving the sclerites widely separated.
Honeypot ant | Anatomy
The myotome is that part of a somite that forms the muscles of the animal. Each myotome divides into an epaxial part ("epimere"), at the back, and a hypaxial part ("hypomere") at the front. The myoblasts from the hypaxial division form the muscles of the thoracic and anterior abdominal walls. The epaxial muscle mass loses its segmental character to form the extensor muscles of the neck and trunk of mammals. In fishes, salamanders, caecilians, and reptiles, the body musculature remains segmented as in the embryo, though it often becomes folded and overlapping, with epaxial and hypaxial masses divided into several distinct muscle groups.
Somite | Myotome
Abdominal exercises are useful for building the abdominal muscles. This is useful for improving performance with certain sports, back pain, and for withstanding abdominal impacts (e.g., taking punches). According to a 2011 study, abdominal muscle exercises are known to increase the strength and endurance of the abdominal muscles. It has been highly disputed whether or not abdominal exercises have any reducing effect on abdominal fat. The aforementioned 2011 study found that abdominal exercise does not reduce abdominal fat; to achieve that, a deficit in energy expenditure and caloric intake must be created—abdominal exercises alone are not enough to reduce abdominal fat and the girth of the abdomen.
Abdominal exercise | Effects
There are five pairs of walking legs, or pereiopods, diminishing in size from front to back. There are no chelae (claws), although the last segment may be able to grip against an extension of the previous segment in some cases (subchelate). The first four pairs are similarly arranged, extending forwards and downwards to be used in walking; the fifth pair is directed upwards. The abdomen bears five pairs of pleopods, of which the first are modified for use in copulation in the males.
Neoglyphea | Appendages
The abdomen has six segments, the front five each having a pair of pleopods (swimming legs). These are biramous (branched) and bear filamentous gills. The sixth segment bears a pair of large uropods which, together with the flexible, six-spiked telson, forms a broad tailfan.

Siphlonurus lacustris | Introduction
There are 7 pairs of legs, corresponding to the 7 segments of the thorax. The short abdomen consists of 6 segments. On the ventral side of the abdomen there are two whitish pseudo-lungs, connected with pores to the outside air. At the rear end there is a small telson flanked by a pair of appendages known as uropods.
Porcellio scaber | Description
Like other "Thelenota," "T. rubralineata" contains calcareous spicules in the form of granules and branched rods. Located throughout the body wall, these structures serve as both structural support and defense from predators. Two Polian vesicles provide the basis for locomotion. 5 longitudinal muscles are broad, V-shaped, and attached to the body wall. A short digestive tract, two narrow respiratory trees, and a small circulatory system running parallel to the intestines is also present. When in motion, the lateral protuberances play a role in walking. When disturbed, "T. rubralineata" bends its body in a helical fashion, arranging its mouth close to the anus, and assumes this position for up to 10 minutes or longer, then moves again.

It likely relied on support from the animal's abdominal musculature.
Caseidae | Characteristics
In the stretched out position, the animal can, slow and cautiously, with the use of his six legs, move forward over a variety of terrains (it can potentially climb or descend steep stairs, plow through bushes, or scramble over boulders). However, when it must cover a great distance, and has a relatively flat path to his disposal, he pushes his head to the ground and rolls himself up with lightning speed, at which time he pushes himself off with his legs- for as much as they can still touch the ground. In the rolled up state it exhibits the form of a discus, of which the eye posts are the central axle.
Curl-up | Translation
Many birds and other animals have a specialised stomach in the digestive tract called a gizzard used for grinding up food. Another feature not found in the human but found in a range of other animals is the crop. In birds this is found as a pouch alongside the esophagus. Other animals including amphibians, birds, reptiles, and egg-laying mammals have a major difference in their GI tract in that it ends in a cloaca and not an anus.

The abdomen of the wētā is the largest and simplest part of its body. It is round, smooth, and lacks appendages except at its rear end. Because of this its functions are mainly internal, serving as an expandable container for the sex organs and digestive organs.

In the "Saitis" group, the third leg is longer and the first leg unspecialized. In the "Jotus" group the first leg is longer and specialized. In both "Maratus" and some "Hypoblemum" in the "Maratus" group, the abdomen is raised during courtship, but only "Maratus" has a colorful dorsal plate.
Maratus | Phylogeny
This is achieved by rubbing projections on the abdominal skin against the inner surface of the cocoon.
Gadirtha inexacta | Introduction
At the front end of the gut, about from the animal's front in an average specimen about long, there was a feeding apparatus that consisted of two (or in rare large specimens three) rows of backward-pointing conical teeth. The feeding apparatus was tough enough to be frequently preserved, but unmineralized and fairly flexible.

The cephalothorax is quite flat, the carapace rather elongate oval and slightly flared near the front. The whole carapace is orange, with a black fringe around the eyes. The yellow brown abdomen is long and narrow, rounded at the front, with long straight, slightly diverging sides that curve to a point near the spinnerets. Several round tufts of white hair are found in pairs. The first two leg pairs are enlarged with weak ventral spines. The legs are generally yellow, with black tinging at the first pair.
Jerzego alboguttatus | Description
The pelvis and shoulder girdles are arranged differently from those of lizards, as is the case with other parts of the internal anatomy and its scales.
Tuatara | Spine and ribs
The anus is on the dorsal surface just in front of the posterior sucker. The body wall includes strong transverse, longitudinal and diagonal muscles which give the animal great flexibility and extensibility.
Clitellata | Characteristics
The term abdominis is an old Latin term for abdomen. In modern times, it is still used in anatomical classification of muscles in the human abdomen such as:

Other animals include rhinoceroses and three-toed horses.
Panraogallus | Introduction
In another randomized study, scientists divided 24 sedentary adults, ages 18–40, into an exercise group and a control group. The exercise group added 7 abdominal exercises, 2 sets of 10 reps each, 5 days a week, for 6 weeks, into their daily routines. The scientists discovered that at the end of the 6 weeks, through comparing a variety of endurance tests, body composition tests, and anthropometrics, the subcutaneous fat around the abdominal region did not shrink. However, muscular endurance of the core region did improve when comparing the before and after of the number of sit-ups between the post-study exercise group and control group.

The legs are long, thin, relatively spineless, and do not have trichobothria. They have three pairs of spinnerets, the longest of which is toward the head. Instead of book lungs, they have two pairs of tracheal spiracles. The elongate abdomen bears a hardened ridge above the pedicel running in a zigzag pattern that is more clearly defined in males than females. The pedipalp on males is oval and bag-like with a thin spermatophore. The female pedipalp does not have a claw.

Other positions and techniques have been developed to produce specific effects and to address specific parts of the body. For example, a "head pull" permits gentle traction and mobilization of the neck, "seaweed position" permits mobilization and rotation of the spine and hips, and "full saddle" permits stretching and massage of the side body and limbs.

The stomach is an organ found in animals. Stomach may also refer to:

Some of the Transvaal specimens also preserved large patches of bony scutes or scales around the body. The scutes on the belly of the animal were arranged in parallel diagonal rows which converged at the midline of the body and diverged as the rows stretched towards the tail. Each scute had a ridge running down the middle, and the scutes further towards the midline overlapped the ones further out. Along the midline, a row of flat and wide scales stretched from the throat to the tail. While these belly scales were made of bone, scales on other parts of the body had less bone structure and were probably made of keratin instead.

7). This entirely passive bulging (and shrinking during exhalation) of the abdomen during normal breathing is sometimes referred to as "abdominal breathing", although it is, in fact, "diaphragmatic breathing", which is not visible on the outside of the body. Mammals only use their abdominal muscles only during forceful exhalation (see Fig. 8, and discussion below). Never during any form of inhalation. As the diaphragm contracts, the rib cage is simultaneously enlarged by the ribs being pulled upwards by the intercostal muscles as shown in Fig. 4. All the ribs slant downwards from the rear to the front (as shown in Fig.

Crocodiles, alligators, and ducks showed elevated aerobic capacity following exercise training. No effect of endurance training was found in most studies of lizards, although one study did report a training effect. In lizards, sprint training had no effect on maximal exercise capacity, and muscular damage from over-training occurred following weeks of forced treadmill exercise.

"Terrestrisuchus" is also known to have had tightly packed gastralia, or belly ribs. Its tail was particularly long, about twice the length of the head and body combined with an estimated 70 caudal vertebrae in total, and may have been used as a balance allowing the animal to rear up and run on its hind legs for brief periods.
Terrestrisuchus | Description
"lie on your back / legs splayed as far apart as comfortable / arms 90 degrees to your body / palms upwards / eyes closed / simultaneously (with a quick movement) raise your torso and legs (legs straight and locked at the knee) / simultaneously clap feet together and hands together (arms are straight and locked at the elbow) / in the moment of clapping, open eyes wide and shout Ra! (roll the 'R' to enunciate fiercely) / when clapping feet and hands, eyes, hands, and feet should be at the same height – feet and hands meet at the same level as your eyes; and at this point your bottom is all that is touching the floor / it is important that the back is kept absolutely straight / try to achieve an angle of 45 degrees to the floor, but NOT by bending your back – bending the back will result in injury! / relax back into the starting position and repeat"

In the mid-line a slight furrow extends from the xiphoid process above to the pubic symphysis below, representing the linea alba in the abdominal wall. At about its midpoint sits the umbilicus or navel. The rectus abdominis on each side of the linea alba stands out in muscular people. The outline of these muscles is interrupted by three or more transverse depressions indicating the tendinous intersections. There is usually one about the xiphoid process, one at the navel, and one in between. It is the combination of the linea alba and the tendinous intersections which form the abdominal "six-pack" sought after by many people.
