Where is SJ-3 located?

SJ-3, also known as Zhongzhu, is located between the fourth and fifth metacarpal bones, specifically in the space proximal to the metacarpophalangeal joint. This point is situated on the back of the hand, making it a useful point for affecting the San Jiao (Triple Burner) channel, which is involved in various functions including managing water pathways and the distribution of qi.

The positioning of SJ-3 is crucial for practitioners as it plays a significant role in addressing conditions related to the shoulder, arm, and other areas affected by this channel. Recognizing the anatomical landmarks in this region allows for precise needling and greater effectiveness of treatment. Other options refer to different anatomical locations that do not pertain to SJ-3, emphasizing the unique placement of this acupuncture point.
