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

• A. KD 3
• B. BL 67
• C. KD 1
• D. BL 66

Answer: (B)

The test is about exact toe-nail anatomy used to pinpoint a Bladder channel point on the foot. On the little toe, the dorsal surface near the nail is divided into precise spots by lines that run along the nail border and across the base of the nail. The point described as being at the junction of those lines, about 0.1 cun from the nail corner, corresponds to Bladder point on the little toe at the nail corner. This is why that option is the correct one.

KD-3 sits near the medial ankle on the kidney channel, not at the nail area. KD-1 is on the sole of the foot, far from the nail region. The other bladder point near the little toe is in a nearby area, but not at the nail corner itself, so it doesn’t match the given description.
