Which GB point lies on the anterior border of the fibula four cun above the lateral malleolus?

• A. GB39
• B. GB38
• C. GB37
• D. GB36

Answer: (A)

The position is determined by the landmarks on the lower leg—the fibula and the lateral malleolus. Four cun above the lateral malleolus along the anterior border of the fibula sits on the Gallbladder channel and is the point known as the marrow-related point on this meridian. It’s placed there because the GB channel runs along the lateral side of the leg, and this location corresponds to four cun up from the ankle on the perpendicular line of the fibula’s anterior border. The four-cun measure makes this a distinct spot, separating it from other nearby GB points that lie at different heights or on different borders. This point is the Hui Meeting point of marrow, often used for marrow- and bone-related issues, and for strengthening the lower limb.
