If the spinous process is T9, which BL point is 1.5 cun lateral?

• A. BL16
• B. BL17
• C. BL18
• D. BL19

Answer: (C)

The key idea is that Back Shu (Bladder channel) points lie 1.5 cun lateral to the spinous processes and align with the corresponding Zangfu organs along the spine. The Liver Shu point is BL18 and is located at the level of the ninth thoracic vertebra. So when the spinous process is at T9, moving 1.5 cun to the side lands you on BL18. The other options correspond to Back Shu points for different organs at other spinal levels, so they would not be at the T9 level.
