Questions: With what part of the scapula does the humerus articulate? subscapular fossa glenoid cavity supraspinous fossa scapular spine Submit Request Answer

The answer is the second one: the glenoid cavity.

Explanation for each option:

1. Subscapular fossa: This is a large, slightly concave surface on the anterior side of the scapula, but it does not articulate with the humerus.
2. Glenoid cavity: This is the shallow depression on the lateral aspect of the scapula that articulates with the head of the humerus to form the shoulder joint.
3. Supraspinous fossa: This is a concave surface located above the spine of the scapula, but it does not articulate with the humerus.
4. Scapular spine: This is a prominent ridge running across the posterior surface of the scapula, but it does not articulate with the humerus.

Summary: The humerus articulates with the glenoid cavity of the scapula.
