KD-12 is located on the lower abdomen, 4 cun below the umbilicus, 1 cun superior to the superior border of the symphysis pubis, 0.5 cun lateral to the midline.

• A. KD-11
• B. REN-3
• C. KD-13
• D. KD-12

Answer: (D)

Understanding how to locate points on the abdomen relies on precise measurements from landmarks like the umbilicus, the midline, and the pubic region. This description places the point 4 cun below the umbilicus and about 0.5 cun to the side of the midline, which identifies it as KD-12 on the kidney channel. Being off the midline differentiates it from REN-3, which sits on the midline, and from KD-13, which is located more superior or inferior on the same general area but at a different distance from the umbilicus. KD-11 would be located farther below the umbilicus (5 cun), not at 4 cun. The combination of 4 cun below the umbilicus and the lateral offset locates it specifically as KD-12, near the lower abdomen just above the pubic region.
