Which point on the thigh lies on a line between the lateral border of the patella and the anterior superior iliac spine, in a depression 6 cun proximal to the superior border of the patella?

• A. ST 32
• B. ST 31
• C. ST 33
• D. ST 34

Answer: (A)

The point described is located on the Stomach channel along the line from the lateral border of the patella to the anterior superior iliac spine, in a hollow about 6 cun above the upper edge of the patella. That precise position corresponds to ST-32. It sits in a shallow depression between the thigh muscles (between rectus femoris and vastus lateralis), which is why you can palpate a hollow there when the leg is relaxed.

The other options lie at different heights along that same line or in nearby regions, so they do not match the exact 6-cun-up location from the patella's upper border.
