Which acupuncture point is located in the third intercostal space, 2 cun lateral to the midline?

• A. KD 25
• B. KD 26
• C. KD 24
• D. KD 23

Answer: (C)

The key idea is matching a point’s exact location on the chest using intercostal space and distance from the midline. KD-24 sits in the third intercostal space (the space between the third and fourth ribs) and is 2 cun lateral to the midline. So the description “in the third intercostal space, 2 cun lateral to the midline” directly identifies this point. To locate it, find the midline of the chest, move down to the third intercostal space, then measure two cun outward from the midline. The other listed points lie in different intercostal spaces or at different lateral positions, so they do not fit the given description.
