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

• A. BL 63
• B. BL 62
• C. BL 64
• D. BL 65

Answer: (A)

On the Bladder channel, locations along the lateral side of the foot are defined by landmarks around the base of the toes and the ankle. The point that sits in the small hollow just behind the tuberosity (the bump) of the fifth metatarsal bone is BL63. That exact position—lateral foot, depression behind the base of the fifth metatarsal—is what identifies this point. The other nearby BL points lie at different landmarks (for example, below the lateral malleolus or around other metatarsal areas) and do not occupy that posterior depression behind the fifth metatarsal tuberosity, so they don’t match this description.
