Which GB point is posterior to the ear along a curved line from GB-9 to GB-12, located about one third of the distance between GB-9 and GB-12?

Which GB point is posterior to the ear along a curved line from GB-9 to GB-12, located about one third of the distance between GB-9 and GB-12?

• A. GB 10
• B. GB 11
• C. GB 12
• D. GB 13

Answer: (A)

The key idea is the path of the Gall Bladder channel behind the ear, which runs along a curved line from GB9 toward GB12. Along that route, the points appear in sequence: GB10 first, then GB11, and finally GB12 at the end near the mastoid. If you’re about one third of the way from GB9 to GB12, you’re at GB10. GB11 would be a bit farther along toward GB12, GB12 is the endpoint behind the ear, and GB13 lies outside this posterior segment.
