Question

Difference between glanoid cavity and acetabulum

Answer 1

The glenoid cavity is the shoulder structure that serves as the “socket.” The humeral head fits into the shallow glenoid cavity, providing the “ball” to make up the ball and socket joint. Compared to the hip “socket,” or acetabulum, the lack of depth in the cavity affords the humerus complete rotation about the joint.
