Which Liver point is on the mamillary line, in the sixth intercostal space, 4 cun lateral to the midline?

• A. LV 13
• B. LV 14
• C. LV 12
• D. CV 1

Answer: (B)

The location hinges on two reference lines: the mamillary line and the intercostal spaces. The mamillary line is a vertical line 4 cun lateral to the midline that runs through the nipple. The Liver point on this line in the sixth intercostal space, exactly 4 cun from the midline, sits here. This is LV14. Other Liver points lie in different regions (for example, LV13 is lower on the abdomen near the costal margin, LV12 is farther lateral on the chest, and CV1 is at the perineum), so they don’t match the described chest location. LV14 is the point described.
