Which point is on the radial side of the index finger, in the substantial depression proximal to the head of the second metacarpal bone?

• A. LI 2
• B. LI 5
• C. LI 7
• D. LI 3

Answer: (D)

Precise point location on the Large Intestine channel is tested here. The point sits on the radial side of the index finger in a deep hollow just proximal to the head of the second metacarpal bone. That specific location corresponds to LI-3, the San Jian point on the LI channel. The LI channel runs along the dorsum of the hand toward the forearm, and this depression at the base of the index finger is the classic landmark for this point.
