Cartilaginous joints

Hyaline cartilage, or fibrocartilage, connects the bones of these joints; joints of this type separate the vertebrae of the vertebral column; the symphysis pubis is also an example; these joints allow limited movement (p. 155).

condyloid joint

saddle joint

gliding joint

In this type of synovial joint the articulating surfaces are flat or slightly curved; most of the joints within the wrist and ankle belong to this group (p. 156).

Synovial Joints

Most joints within the skeletal system are of this type and allow free movement (p. 155).

ball-and-socket joint

The joint shown above allows a wider range of motion than does any other kind, permitting movements in all planes and rotation. What type of synovial joint is this? (p. 156).
