Between the 4th and 5th metatarsal bones, in the depression proximal to the metatarsal heads, on the medial side of the tendon of extensor digitorum longus?

• A. GB41
• B. GB42
• C. LV2
• D. GB44

Answer: (B)

This question tests precise dorsum-of-foot point location using nearby bones and tendons. The described spot—between the 4th and 5th metatarsal bones, in the depression just proximal to the metatarsal heads, on the medial side of the tendon of the extensor digitorum longus—matches the Gallbladder point that lies in that intermetatarsal space Medial to the EDL tendon. That is GB42.

Other nearby points sit at different landmarks: GB41 is located in a similar region but on the lateral side of the EDL tendon; LV2 sits between the first and second toes; GB44 is at the lateral edge near the nail bed of the little toe.
