Which point is on the medial side of the foot, distal and inferior to the base of the first metatarsal bone?

• A. SP 2
• B. SP 3
• C. ST 42
• D. ST 44

Answer: (C)

The point in question sits on the stomach channel along the dorsum (top) of the foot, on the medial side, in a hollow just distal and inferior to the base of the first metatarsal bone. That precise spot corresponds to ST-42, the yuan-source point of the stomach channel. It’s the only option that lies in that medial-dorsal region near the base of the first metatarsal, so it matches the description exactly. The other points are located in different areas: some near the big toe on the spleen channel or between the toes, not in this medial-dorsal location near the first metatarsal base.
