Which CV point is located 3 cun above the umbilicus and 5 cun below the sternocostal angle?

Which CV point is located 3 cun above the umbilicus and 5 cun below the sternocostal angle?

• A. CV9
• B. CV3
• C. CV11
• D. CV8

Answer: (C)

This item tests locating Ren (Conception Vessel) points along the midline using bony landmarks and cun measurements. The sternocostal angle (Angle of Louis) marks a high chest level, and from there down to the umbilicus is about 8 cun. So being 5 cun below that angle puts you 3 cun above the umbilicus. The Ren point sequence above the umbilicus increases in 1-cun steps, with the point 3 cun above the umbilicus corresponding to CV11. Therefore, the described location matches CV11.
