Which SI point is located at the ulnar border of the wrist, in the depression between the head of the ulna and the triquetral bone?

• A. SI 11
• B. SI 6
• C. SI 7
• D. SI 5

Answer: (D)

The important idea is recognizing the wrist landmarks used to locate SI points. This point sits on the ulnar (little finger) side of the wrist in the hollow between two bones: the head of the ulna and the triquetral bone. That specific depression is what you palpate to identify the point, making it the Yang Gate point.

So, the correct location describes the precise wrist depression between the head of the ulna and the triquetral bone, which is unique to this point. The other options correspond to different spots along the meridian or different anatomical landmarks, not this particular wrist depression.
