Which BL point is on the lateral side of the foot, in the depression posterior and inferior to the head of the fifth metatarsal bone?

• A. BL 63
• B. BL 64
• C. BL 62
• D. BL 60

Answer: (B)

This question tests precise surface anatomy for BL (Bladder) channel point locations on the foot. The description places the point on the lateral side of the foot, specifically in a depression that is behind and below the head of the fifth metatarsal bone. The point that sits in that exact spot is Jinmen, a lateral-foot BL point. To find it, locate the head of the fifth metatarsal (the base area near the little toe) and palpate posterior and inferior to it to feel the shallow hollow where Jinmen lies.

The other BL points listed are in different locations along the foot and ankle, not in this particular depression behind the head of the fifth metatarsal, so they don’t match this description.
