Questions and Answers

What is unique about the lining of a joint cavity?

It is lined by connective tissue only
It is lined by a perichondrium
It is lined by articular cartilage and a synovial membrane (correct)
It is lined by an epithelium

What is the function of the synovial fluid in a joint cavity?

To provide structure to the joint
To maintain metabolic needs of articular cartilage (correct)
To produce the synovial membrane
To facilitate movement between bones

Why is the repair of articular cartilage a concern?

Because it requires a synovial membrane
Because it is very slow and only occurs via interstitial growth (correct)
Because it requires a perichondrium
Because it is too fast and can lead to joint instability
