Which GB point is in the depression just posterior and inferior to the mastoid process?

• A. GB 11
• B. GB 12
• C. GB 13
• D. GB 14

Answer: (B)

Understanding the landmarks is key here. GB12 sits exactly in a shallow hollow that lies behind and slightly below the mastoid process—the bony bump you can feel behind the ear. That specific depression matches the description given, so this point is GB12. The other GB points referenced are located in different regions around the head and do not lie in that mastoid depression, which is why they don’t fit the description.
