Where is BL-10 located in relation to the trapezius?

The point BL-10, also known as Tian Zhu, is located at the base of the skull. To understand its precise placement in relation to the trapezius muscle, it's important to visualize the anatomical landmarks. BL-10 is situated just lateral to the edge of the trapezius. This positioning means that when you identify the trapezius muscle, BL-10 can be found slightly to the side of its lateral border, which is crucial for proper acupuncture needle placement.

In the context of other potential answers, being medial to the trapezius edge would imply that the point is located closer to the midline of the body than the trapezius muscle, which is not accurate. Likewise, the options referring to superior or inferior placements would indicate that the point lies above or below the trapezius muscle's edge, which also does not align with its actual anatomical location. Therefore, the understanding of BL-10 being lateral to the trapezius edge highlights its specific anatomical relationship, important for effective acupuncture treatment.
