Where is BL-44 located in relation to other points?

BL-44, also known as Shentang, is located in the vicinity of the back and is associated with the bladder meridian. To understand its correct placement in relation to other points, it is essential to recognize the anatomical positioning of the bladder points on the back.

BL-44 is situated at the level of the 5th thoracic vertebra (T5) and is precisely positioned lateral to BL-15, which corresponds to the pericardium point at the same spinal level. This positioning indicates that BL-44 will always be found to the side of BL-15.

In contrast, the other points mentioned each correspond to different anatomical locations. BL-20 is found at T9, BL-13 at T3, and BL-18 at T10. Since BL-44 is at T5, it is not laterally positioned to these points, making them less relevant in the context of this question.

Thus, recognizing the anatomical arrangement and levels of these points establishes that the correct answer is the one indicating BL-44's lateral positioning to BL-15.
