Which Back Shu point is located 1.5 cun lateral to T11?

The Back Shu points correspond to the (yang) organs along the Bladder channel and are located on the back side of the body, typically 1.5 cun lateral to the spinous processes of the vertebrae associated with specific internal organs.

In this case, the correct choice highlights that the Back Shu point located 1.5 cun lateral to T11 is the one associated with the spleen, which is BL-20 (Spleen Back Shu). This point plays a crucial role in addressing issues related to the spleen, such as digestive disorders or deficiencies, and it is vital for practitioners to accurately identify these points for effective treatment.

BL-19, which is the Back Shu point for the liver, is located 1.5 cun lateral to T10. BL-21 corresponds to the stomach and is found 1.5 cun lateral to T12. BL-22, the triple warmer Back Shu point, is located 1.5 cun lateral to L1. This demonstrates the importance of anatomical landmarks in locating these vital acupuncture points accurately. Remembering the relationship between the vertebral levels and their corresponding Back Shu points is essential for effective acupuncture practice.
