Which LU point lies on the radial aspect of the forearm, approximately 1.5 cun proximal to LI-5, in the cleft between the tendons of brachioradialis and abductor pollicis longus?

• A. LU-9
• B. LU-8
• C. LU-7
• D. LU-6

Answer: (C)

This question tests precise point localization along the Lung channel on the forearm. The description matches LU-7 exactly: it sits on the radial (thumb) side of the forearm in the groove between the tendons of brachioradialis and abductor pollicis longus, about 1.5 cun proximal to LU-5 (the elbow crease). That combination of anatomical landmarks and the measured distance is the standard way to identify this point.

LU-7 is the proximal forearm point used on the Lung channel and is distinct from the wrist-point locations further down the forearm (and away from the brachioradialis–abductor pollicis longus cleft). So the landmark set given—radial forearm, in that specific tendon cleft, 1.5 cun above LU-5—points to LU-7. This point is also known for functions such as dispersing exterior wind and addressing issues like cough or neck/stiffness, which helps reinforce why its location is commonly emphasized in practice.
