A ball and socket joint (enarthrosis, spheroidal joint) is a joint in which the distal bone is capable of motion around an indefinite number of axes, which have one common center.
In a ball-and-socket (or spheroid) joint, the ball-shaped surface of one bone fits into the cuplike depression of another. Movements are flexion-extension, abduction-adduction, and rotation (triaxial) and circumduction;
Examples of this form of articulation are found in the hip and shoulder.
