What is the distance from the umbilicus to the pubic symphysis?

The distance from the umbilicus to the pubic symphysis is typically measured as 5 cun in traditional Chinese medicine. This measurement is based on the anatomical reference points used in acupuncture and relates to the concept of "cun" as a unit of measurement, which can vary based on the individual's body size.

In clinical practice, understanding this distance is essential because it helps practitioners locate acupuncture points accurately on the body. The umbilicus serves as a key landmark, and knowing that the pubic symphysis lies 5 cun below facilitates the precise placement of needles for effective treatment. This understanding of anatomical landmarks and their corresponding measurements is critical for practitioners to ensure both safety and therapeutic effectiveness in acupuncture treatment.
