KD-17 is located on the upper abdomen, 3 cun above the umbilicus, 0.5 cun lateral to the midline. Which point is this?

• A. KD-16
• B. KD-17
• C. REN-11
• D. KD-18

Answer: (B)

Understanding how to locate points uses precise measurements from the umbilicus and the body's midline. A point described as being on the upper abdomen, 3 cun above the umbilicus and 0.5 cun lateral to the midline, sits on the Kidney channel at that specific vertical level and offset. That exact description corresponds to KD-17. Other options don’t fit the described coordinates: KD-16 is at the level of the umbilicus but 0.5 cun lateral to the midline; REN-11 is on the midline and about 5 cun above the umbilicus; KD-18 is located higher than KD-17 (about 2 cun above the umbilicus) and 0.5 cun lateral to the midline. Hence, the given location uniquely identifies KD-17.
