Gliding joints __________.

include the articular processes of vertebrae, the intercarpal and intertarsal joints

Structural classification of joints __________.

Synovial joint cavities are the only important exceptions to the rule that cavities in the body are always lined with epithelia. The synovial membrane consists of

loose connective tissue.

A bursa differs from the synovial cavity of a joint in that it
