Which BL point lies on the buttock, 3 cun lateral to the sacro-coccygeal hiatus?

• A. Bl 52
• B. Bl 50
• C. Bl 54
• D. Bl 53

Answer: (C)

Understanding how BL points are located uses identifiable landmarks and cun measurements. The sacral hiatus is a palpable landmark at the lower spine, and moving 3 cun laterally from that point places you in the gluteal region where a Bladder channel point sits.

Bladder 54 is located in the buttock, in the depression formed by the gluteus maximus, about 3 cun lateral to the sacro-coccygeal hiatus. This exact description matches the question, which is why this point is the correct one. The other listed BL points lie in different regions along the back or pelvis and do not correspond to that buttock location.
