Which GB point lies directly below the nipple in the seventh intercostal space?

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

Answer: (D)

GB24 is the gallbladder front-mu point, and its exact location is the seventh intercostal space directly below the nipple. That precise chest level is what identifies it, so this point sits on the chest wall in line with the nipple and along the gallbladder meridian.

Nearby chest points in the same region are higher and more lateral: those in the fifth intercostal space along the lateral chest, with one cu­n anterior to the other. A point on the lateral abdomen near the iliac region sits well below the chest, not in the seventh intercostal space.

So the description—seventh intercostal space, directly below the nipple—matches GB24, making it the correct choice.
