Out of the following, which is the measure for the lateral leg?

The lateral aspect of the leg is measured as approximately 15 cun, which is significant for locating acupuncture points and understanding the anatomy in this region. A cun is a traditional Chinese measurement that varies depending on the practitioner's own measurements, usually based on the width of the patient's thumb or their body's anatomical landmarks.

Specifically, the measurement of 15 cun for the lateral leg is relevant when identifying points along the bladder and gallbladder channels, which run along this part of the leg. It allows practitioners to accurately place needles to achieve therapeutic effects efficiently.

Choosing an alternative measurement, such as 16 cun, 12 cun, or 10 cun, would not align with the established anatomical references used in acupuncture practice for this area. Understanding these nuances helps ensure that acupuncture points are effectively located for optimal treatment outcomes.
