LI-11 is located between which anatomical landmarks?

LI-11, also known as Quchi, is an important acupuncture point located in the elbow region. This point is specifically situated midway between LU-5 (Located at the cubital crease of the elbow, in the depression lateral to the biceps tendon) and the lateral epicondyle of the humerus. The positioning of LI-11 in this way is clinically significant because it allows practitioners to understand its relationship to both nearby points and larger anatomical structures, making it easier to locate during treatment.

This particular location serves not just a purely anatomical function but also correlates with various physiological and therapeutic contexts, such as its use in the regulation of heat, cooling blood, and influencing superficial pathogens. Recognizing the midway point between LU-5 and the lateral epicondyle allows acupuncturists to enhance their accuracy when needling or applying techniques for therapeutic benefit.

The other choices relate to different anatomical landmarks that do not correspond to the correct location of LI-11. They might refer to distinct areas on the body but do not provide the accurate geographical reference needed for LI-11. Thus, understanding the specific location of LI-11 enhances the ability to apply acupuncture effectively in practice.
