Which point on the abdomen is 2 cun lateral to the midline and 1 cun superior to the umbilicus, level with REN-9?

• A. ST 21
• B. ST 22
• C. ST 23
• D. ST 24

Answer: (D)

Locating abdomen points uses two landmarks: the midline and the level of the umbilicus, with cun as the unit. A point 2 cun lateral to the midline sits on the left or right of the midline, not on it, while being positioned on a horizontal line that is 1 cun above the umbilicus. That particular plane aligns with REN-9 on the midline. So a point that is 2 cun from the midline and on the plane level with REN-9, which is 1 cun above the umbilicus, is ST-24. This combination of horizontal distance from the midline and vertical position is what uniquely identifies ST-24 in the abdominal map. Other nearby ST points occupy different vertical levels, so they wouldn’t match this exact description.
