Which BL point is located 3 cun lateral to the midline, level with the lower border of the spinous process of T7 and at the same level as Geshu BL-17?

Which BL point is located 3 cun lateral to the midline, level with the lower border of the spinous process of T7 and at the same level as Geshu BL-17?

• A. Bl 45
• B. Bl 46
• C. Bl 47
• D. Bl 48

Answer: (B)

The location described matches a bladder channel point that sits 3 cun lateral to the midline at the same thoracic level as Geshu (the point at T7). Geshu is at T7, about 1.5 cun from the midline. Doubling that lateral distance to 3 cun brings you to BL-46, the Diaphragm Gate, on the bladder channel. That makes BL-46 the best answer for a point at 3 cun lateral, level with T7 and aligned with Geshu BL-17. The other options correspond to different thoracic levels or different distances from the midline, so they don’t fit this specific description.
