Which scapular feature forms the shoulder joint with the head of the humerus?

Explanation:
The shoulder joint is formed where the head of the humerus sits in a shallow socket on the scapula called the glenoid cavity. This glenoid socket and the humeral head form the glenohumeral joint, a ball-and-socket arrangement that allows a wide range of motion. The other scapular features—scapular spine, acromion, and coracoid process—do not participate in the articulation with the humeral head. The acromion and coracoid serve as attachment points or form other joints, and the scapular spine is a posterior ridge, not the joint surface.
