Which CV point is on the midline of the abdomen, 3 cun above the umbilicus and 5 cun below the sternocostal angle?

• A. CV3
• B. CV11
• C. CV2
• D. CV9

Answer: (B)

This question tests how Ren (CV) points along the midline are located using cun measurements from recognizable landmarks. The sternocostal angle (near the xiphoid) and the umbilicus are two key reference points. The distance from the sternocostal angle to the umbilicus is used to gauge where along the midline a point lies.

If you are 5 cun below the sternocostal angle, you’re roughly 3 cun above the umbilicus (since the segment between the xiphoid area and the navel is about 8 cun). On the midline, the point 3 cun above the umbilicus is Ren11. Ren12 sits 4 cun above the umbilicus, so this location corresponds to Ren11 rather than the others. Therefore, the described position matches the midline Ren point that is 3 cun above the umbilicus and 5 cun below the sternocostal angle.
