Where is Du-5 located in relation to the lumbar vertebrae?

Du-5, also known as "Yao Yang" or "The Lumbar Yang," is located in the lower back area, specifically in relation to the lumbar vertebrae. It is situated at the midline of the body, approximately 1.5 cun below the spinous process of the first lumbar vertebra (L1).

This point is an important reference for practitioners of acupuncture and is often used for issues related to the lower back and kidneys. Since it is located below L1, the correct answer indicates its position relative to the lumbar vertebrae, emphasizing the anatomical landmarks crucial for effective acupuncture practice.

While the other options reference various positions around L1 and T1, they do not accurately represent Du-5’s precise anatomical location beneath the first lumbar vertebra. Such distinctions are essential for correct needle placement and treatment efficacy in therapeutic practice.
