Feedback:
Although as a group they are classified as freely moveable, synovial joints include planar joints, which allow almost no movement (e.g., vertebrocostal joint), and hinge joints, which allow angular movement in one plane (e.g., interphalangeal, knee, and ankle joints). Only the ball-and-socket joints permit movement in all directions (e.g., shoulder or hip joint).
