The medial epicondyle is which option?

• A. Lateral epicondyle
• B. Olecranon process
• C. Radial head
• D. Medial epicondyle

Answer: (D)

The main idea here is recognizing elbow bony landmarks. The medial epicondyle is the inner, or inner-side, bony prominence at the distal end of the humerus. It sits on the medial aspect of the elbow and serves as an attachment for forearm flexor muscles and part of the ulnar collateral ligament. That makes it the correct label for the inner epicondyle.

The other structures are different: the lateral epicondyle is the outer counterpart on the humerus; the olecranon process is the prominent point of the ulna at the back of the elbow; the radial head is the top end of the radius near the elbow.
