What is the measurement from the sternocostal angle to the umbilicus?

The measurement from the sternocostal angle to the umbilicus is considered to be 8 cun in traditional Chinese medicine. The cun is a traditional unit of measurement that is based on the width of a person's thumb. The location of anatomical landmarks is important for acupuncture point identification and treatment strategies.

The distance from the sternocostal angle to the umbilicus represents a key region for identifying various acupuncture points and understanding the layout of the abdomen.

In this context, the other options reflect measurements that either don't correspond to the accepted distance or would misrepresent the standard anatomical understanding. Therefore, understanding this distance as 8 cun is crucial not only for accurate diagnosis and treatment but also for maintaining the integrity of acupuncture practices.
