Which point is located on the dorsal aspect of the index finger, at the junction of lines along the radial border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail?

Which point is located on the dorsal aspect of the index finger, at the junction of lines along the radial border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail?

• A. LI 1
• B. LU 11
• C. LI 2
• D. LI 3

Answer: (B)

The key idea is the precise nail-edge location of the Lung channel’s end point. LU-11 sits on the dorsal aspect of the index finger at the nail area, at the junction where the lines along the nail border meet the base of the nail, about 0.1 cun from the corner of the nail. That exact nail-bed position is what identifies LU-11 on the hand. The other points lie in different locations along the Large Intestine channel or on different parts of the hand, not at this dorsal nail-edge spot.
