ball-and-socket jointThe most freely movable type of synovial joint, in which the ball-like end of one bone (e.g., the humerus, femur) is surrounded by a spherical cartilaginous encasement, or “socket” (e.g., hip joint), or a group of structures that act as a functionally spherical encasement (e.g., shoulder joint), which allows free mobility of the articulating bone.
