Explanation

The shoulder joint (glenohumeral joint) is a ball-and-socket joint, where the rounded head of the humerus fits into the shallow glenoid cavity of the scapula. This structure allows wide range of motion in all directions. Hinge joints bend only one way (like elbows), pivot joints rotate (like the neck), and fixed joints don't move (like skull bones).
