Which GB point lies on the lateral aspect of the lower leg, five cun superior to the prominence of the lateral malleolus, at the anterior border of the fibula?

• A. GB38
• B. GB37
• C. GB35
• D. GB34

Answer: (B)

Locating a Gall Bladder point on the lower leg uses precise distances from the lateral malleolus and the border of the fibula. Five cun above the prominence of the lateral malleolus, on the anterior border of the fibula, corresponds to Guangming, GB37. This position places the point on the outer leg along the Gall Bladder channel, matching its described location.

For context, GB38 is also on the anterior border of the fibula but four cun above the lateral malleolus, GB35 sits on the posterior border of the fibula seven cun above the lateral malleolus, and GB34 lies lower, in a depression just anterior and inferior to the head of the fibula. The described five-cun, anterior-border position identifies GB37 precisely.
