Which point is located on the dorsum of the foot at the junction of the second and third metatarsal bones?

• A. ST 41
• B. ST 43
• C. ST 42
• D. SP 3

Answer: (C)

The key idea is locating a stomach-channel point by its exact position on the dorsum of the foot. This point lies in the depression between the bases of the second and third metatarsal bones, on the dorsal aspect of the foot. That precise spot is what identifies it as ST-42, the stomach channel point found at the junction of those two metatarsals. The other options do not sit at that same junction—their locations are elsewhere on the foot (one up near the ankle, another on a different dorsal site, and one on the medial side)—so they don’t match the description.
