Du-8 is positioned below which thoracic vertebra?

The correct answer is based on the anatomical location of the Du meridian points in relation to the thoracic vertebrae. Du-8, also known as Jinsuo, is situated in the midline of the back at the level of the spinous process of the T9 vertebra. The key detail is that it is located below this specific vertebra, which is why the answer indicates T9.

Understanding the positioning of acupuncture points in relation to vertebral anatomy is essential for practitioners to ensure accurate needle placement and effectiveness of treatment. The identification of Du-8 being specifically beneath T9 emphasizes the importance of anatomical landmarks in acupuncture practice and how they integrate with traditional theories. This knowledge is crucial not only for acupuncture but also for understanding how different points relate to the meridian system and overall healing practices.
