The Humerus

Question

The humerus
A) contains the olecranon process.
B) articulates distally with the ulna.
C) forms a ball-and-socket joint where the olecranon process articulates with the olecranon fossa.
D) articulates with the scapula at the sternomanubrial joint.

Accepted Answer

The humerus articulates distally with the ulna at the elbow joint, forming a hinge joint. The olecranon process is a feature of the ulna, not the humerus. The ball-and-socket joint is formed between the humerus and scapula, specifically at the glenohumeral joint. The sternomanubrial joint is the joint between the sternum and the clavicle, and does not involve the humerus.
