Flashcards in Chapter 7: Joints Deck (41):
What is Articulation(joint)?
A place where bones meet
What are the three classes of joints based on structure?
Describe the fibrous joint
No joint cavity, held together with fibrous C.T.
Describe the Cartilaginous joint
No joint cavity, held together with cartilage
Describe the Synovial joint
Has joint cavity, held together by ligaments
Name the three classes of joints according to the amount of movement they permit.
1.) Synarthrosis: immovable joint
2.) Amphiarthrosis: slightly movable
3.) Diarthrosis: Freely movable
Sutures between skull bones are examples of
Discs between vertebrae are examples of
Attachment of a tooth to its socket in the mandible or maxilla is
More mobile that a suture but less mobile than a joint like elbow is
The symphysis pubis is an example of
The distal end of the tibia/fibula is an example of
The epiphysial plate in growing bone is an example of
Hyaline cartilage that covers ends of articulating bones
It lubicates the joints and nourishes the cartilage
Inner layer of the articulate capsule that produces synovial fluid
Pad of cartilage to help stabilize the joint
Together these form the articulate capsule
Fibrous capsule and synovial membrane
Fluid-filled sac that cushions movements
The joint allowing for the greatest degree of movement
Flat surfaces of the carpals or tarsals move across each other
The joint at the wrist between the radius and carpals
Moves in a single plane at the knee or elbow
He joint between the carpals and the metacarpal of the thumb
The rounded head of the radius moves within the radial notch of the ulna
Movement of the bone around its own axis
Movement away from the midline of the body
Palm faces upward or forward
Downward movement of a body part
Movement toward the body midline
Movement of the mandible or shoulder backward
Turning the palm so it faces downward or backward
Upward movement of a body part
Movement of a distal end of a body part in a circle
Beyond the plane of extension
Movement of the sole of the foot inward
Movement of the foot so the toes point downward
How are arthritis and rheumatism related?
Arthritis is a form of rheumatism
"Wear and tear" arthritis causing deterioration of the articulate cartilage is...
Displacement of the bone from its joint is..
