What is the measure in cun for the lateral leg?

The measure of the lateral leg is determined by specific anatomical landmarks used in acupuncture and body measurement practices. The lateral aspect of the leg can be measured from the lateral malleolus (the bony prominence on the outside of the ankle) to the popliteal fossa (the shallow depression located at the back of the knee).

In traditional Chinese medicine, the distance from the lateral malleolus to the popliteal fossa is typically standardized at 16 cun. This measurement is established based on average anatomical proportions and is used consistently in practice. Recognizing this standard allows practitioners to accurately locate acupuncture points and apply treatment effectively.

The other options provided represent distances that do not match the established standard for this specific anatomical region. Understanding these measurements is critical for practitioners in order to maintain consistency in treatment protocols and ensure the effectiveness of acupuncture therapies.
