Which point is 2 cun proximal to the superior border of the patella, in the tender depression on the bulge of the vastus medialis muscle, directly above Yīnlíngquán SP-9?

• A. SP 10
• B. SP 11
• C. SP 9
• D. SP 6

Answer: (A)

Precise anatomical location along the spleen channel is being tested. SP-10 sits on the medial thigh, in the tender depression on the bulge of the vastus medialis, about 2 cun above the superior border of the patella. It’s the Sea of Blood point, and this description matches exactly: near the knee, on the inner thigh, just above the patella, in the bulge of the vastus medialis, and above SP-9. The other points are situated elsewhere along the leg or thigh and do not share this specific knee-region location. SP-9 is farther down on the lower leg, SP-6 lies on the lower leg as well, and SP-11 is in a different thigh area. Therefore, the described location corresponds to SP-10.
