|
|
|
What is the cartilage pad that covers the surface of a bone inside a joint cavity?
|
articular cartilage
|
|
|
Inflammation of fibrous connective tissue around joints
|
Rheumatism
|
|
|
Inflammation of a joint
|
arthritis
|
|
|
The noninflammatory disorder of moveable joints characterized by deterioration of the articular cartilage and the formation of new bone at the joint surfaces
|
osteoarthritis
|
|
|
What is characterized by the synovial membrane thickening and becoming tender, synovial fluid accumulating, articular cartilage beginning to deteriorate and ossification of joint?
|
rheumatoid arthritis
|
|

|
bunion
|
|
|
The greater the range of motion at a joint
|
the weaker it becomes

rotation
|
|
|
What movement reduces the angle between the articulating elements?
