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
