Which point lies on the dorsum of the hand just proximal to the second and third metacarpophalangeal joints?

Which point lies on the dorsum of the hand just proximal to the second and third metacarpophalangeal joints?

• A. M-UE-24 LUÒZHĚN
• B. N-UE-19 YĀOTÒNGXUÉ
• C. M-UE-46 ZHǑUJIĀN
• D. M-UE-29 ÈRBÁI

Answer: (A)

The key idea here is precise point location on the hand’s dorsum. Luòzhèn is the Luo-connecting point that sits on the dorsum between the bases of the second and third metacarpals, just proximal to the second and third metacarpophalangeal joints. That exact spot matches the description in the question, which is why this point is the correct choice. In contrast, the other named points are located elsewhere on the hand or wrist, not at this dorsal between-two-and-three-metacarpal region.
