Which BL point lies over the second posterior sacral foramen?

• A. BL 32
• B. BL 31
• C. BL 33
• D. BL 34

Answer: (A)

The Bladder channel along the back has four points that sit directly over the posterior sacral foramina, aligning with S1 to S4. These are BL-31, BL-32, BL-33, and BL-34, in order from the first to the fourth foramen. Therefore, the second posterior sacral foramen corresponds to BL-32. The other sacral points align with the remaining foramina: BL-31 over the first, BL-33 over the third, and BL-34 over the fourth.
