Which CV point is on the midline of the abdomen, 4 cun above the umbilicus and midway between the umbilicus and the sternocostal angle?

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

Answer: (C)

Locating these points relies on accurate midline anatomy and cun measurements on the Ren (Conception) vessel. The description given—on the abdomen’s midline, 4 cun above the umbilicus, and halfway between the umbilicus and the sternocostal angle—matches the standard position of Zhongwan (CV12). This point sits on the midline of the upper abdomen at about four cun above the navel, which in typical anatomical schematics places it halfway toward the sternocostal angle. So this description best fits CV12. The other points on the Ren Mai are at different vertical positions along the midline and do not align with this specific 4-cun-above-umbilicus, halfway-to-the-sternocostal-angle location.
