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

• A. KD 22
• B. KD 23
• C. KD 24
• D. KD 25

Answer: (A)

Understanding surface anatomy for point location is about matching two coordinates: the rib-space level and how far the point sits from the midline. The description places the point in the fifth intercostal space, 2 cun lateral to the midline. The point that fits this exactly is the kidney point located at that chest position, two cun out from the midline between ribs five and six. That precise combination of rib-space and lateral distance is what confirms it. The other options lie at different intercostal spaces or at different distances from the midline, so they don’t match the given description as closely.
