Which BL point is located 3 cun lateral to the midline, level with the lower border of the spinous process of the third thoracic vertebra and BL-13?

Which BL point is located 3 cun lateral to the midline, level with the lower border of the spinous process of the third thoracic vertebra and BL-13?

• A. BL 41
• B. BL 40
• C. BL 42
• D. BL 43

Answer: (C)

The location tests knowing that the Bladder channel has points at 3 cun lateral to the midline along the upper back, with each vertebral level hosting a distinct point. BL-13 (the Lung Shu) sits at T3, 1.5 cun lateral to the midline. Moving 3 cun lateral from the midline at the same level identifies the next point along the BL back-curve, which is BL-42 located at T3, 3 cun lateral. So the described spot corresponds to BL-42.
