Which point is on the tip of the olecranon process of the ulna?

• A. M-UE-46 ZHǑUJIĀN
• B. M-UE-1 SHÍXUĀN
• C. M-UE-29 ÈRBÁI
• D. N-UE-19 YĀOTÒNGXUÉ

Answer: (A)

The elbow’s bony tip is a well-known local landmark, and the point that sits exactly at that spot is M-UE-46 ZHǑUJIĀN. This location corresponds to the tip of the olecranon process of the ulna, making it the direct, anatomical match for the question. The other points lie in different regions: SHÍXUĀN is associated with areas on the hand or fingers, ERBÁI is near the elbow crease but not at the olecranon tip, and YĀOTÒNGXUÉ is on the hand’s dorsum for other issues. So the elbow-tip point best fits the described location.
