Which point is between the 4th and 5th metatarsal bones, in the depression proximal to the metatarsal heads, on the medial side of the tendon of m. extensor digitorum longus (branch to little toe)?

Which point is between the 4th and 5th metatarsal bones, in the depression proximal to the metatarsal heads, on the medial side of the tendon of m. extensor digitorum longus (branch to little toe)?

• A. GB43
• B. LV1
• C. GB42
• D. GB41

Answer: (C)

Focusing on precise dorsum-of-the-foot anatomy, this point is defined by both the metatarsal landmarks and a tendon relationship. The location described—between the 4th and 5th metatarsal bones, in a depression proximal to the metatarsal heads, and on the medial side of the extensor digitorum longus tendon that goes to the little toe—matches the standard description of GB42. It sits on the gallbladder channel along the dorsum of the foot, with the key cue being its position medial to the ED longus tendon to the little toe and between those two metatarsals. When locating it, feel for the shallow hollow just proximal to the heads of the 4th and 5th metatarsals and move medially to the tendon; that’s GB42. The other points listed occupy different spots on the foot and do not share this exact combination of bone landmarks and tendon relation, so they don’t fit this description.
