Which point is on the dorsal aspect of the little toe, at the junction of lines drawn along the lateral border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail?

Which point is on the dorsal aspect of the little toe, at the junction of lines drawn along the lateral border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail?

• A. BL 67
• B. KD 2
• C. KD 3
• D. KD 4

Answer: (A)

The key idea is recognizing the terminal point of a channel on the little toe, specifically on the dorsal surface near the nail. The description—on the dorsal aspect of the little toe at the junction of lines along the nail border, about 0.1 cun from the nail corner—matches the Bladder channel’s end point at that location. This point sits at the nail corner area and marks the last point on the Bladder line that runs to the little toe. The other options lie on different channels and in other parts of the foot or ankle, not at the nail corner on the little toe. They’re located along the Kidney channel in locations away from the dorsal nail area, so they don’t fit the described position.
