Which GV point is located on the back of the head on the midline, 1.5 cun directly above Fengfu (DU-16), in the depression directly superior to the external occipital protuberance?

• A. GV 16
• B. GV 15
• C. GV 17
• D. GV 14

Answer: (C)

This question tests precise landmark-based location of a Governing Vessel point along the midline of the back of the head. The point in question sits on the posterior midline, 1.5 cun above the point labeled Fengfu (DU-16), in the hollow just above the external occipital protuberance. That describes GV-17 exactly. The Governing Vessel runs along the midline of the spine and head, and this height places it higher on the occipital region, just where the skull has a small indentation above the bump of the external occipital protuberance. The other options correspond to different heights along the midline, so they do not match this described location.
