Verified step by step guidance

Understand the anatomy of the elbow joint: The elbow is formed by the articulation of three bones—the humerus (upper arm bone), the radius (lateral forearm bone), and the ulna (medial forearm bone). The olecranon process is a prominent structure of the ulna that forms the bony point of the elbow.

Review the location and function of the olecranon process: The olecranon process is the large, curved projection at the proximal end of the ulna. It serves as the insertion point for the triceps brachii muscle and is palpable as the bony prominence at the back of the elbow.

Compare the olecranon process to other structures listed: The head of the radius is located at the proximal end of the radius and contributes to the elbow joint but does not form the point of the elbow. The medial epicondyle of the humerus is a bony projection on the humerus but is located on the inner side of the elbow. The coronoid process of the ulna is another projection of the ulna but is located anteriorly and does not form the point of the elbow.

Identify the correct structure based on anatomical position and function: The olecranon process of the ulna is the structure that forms the point of the elbow, as it is the most posterior and prominent bony feature of the elbow joint.

Conclude that the olecranon process of the ulna is the correct answer, as it matches the description of forming the point of the elbow and is distinct from the other listed structures.
