Which bony landmark is formed at the distal end of the humerus where it broadens laterally and medially?

• A. Epicondyle
• B. Trochlea
• C. Capitulum
• D. Condyle

Answer: (A)

This item tests understanding of the distal humerus where the bone widens to form the elbow joint. The expanded distal end is the humeral condyle, which includes two articular surfaces: the lateral capitulum that articulates with the head of the radius, and the medial trochlea that articulates with the ulna. The epicondyles are the raised prominences on the sides just above this surface and serve as attachment points for ligaments and forearm muscles, not the main broad articulation. So the landmark formed at the distal end where the bone broadens medially and laterally is the condyle.
