Question

Quizplus · Accepted Answer

The head of the humerus articulates with the scapula at the glenoid cavity, also known as the glenoid fossa or the glenoid. This is a shallow depression on the lateral surface of the scapula where the humerus sits and moves during shoulder joint motion. The coracoid process is a projection on the scapula that serves as a point of attachment for muscles and ligaments, but does not directly articulate with the humerus. The subscapular fossa is a concave depression on the anterior surface of the scapula, and does not play a role in the shoulder joint. The acromion process is a bony projection on the scapula that forms the highest point of the shoulder and serves as a site of attachment for the clavicle, but does not directly articulate with the humerus.
