Which LU point is on the cubital crease of the elbow, in the depression at the radial side of the tendon of biceps brachii?

• A. LU-5
• B. LU-6
• C. LU-7
• D. LU-8

Answer: (A)

The elbow crease description points to the Lung channel’s He-Sea point. This spot sits in the cubital crease, in the hollow on the radial (thumb) side of the tendon of the biceps brachii. That precise location is what defines LU-5. Because it’s the He-Sea point at the elbow, it’s the go-to point for issues involving the Lung channel’s path through the arm and for elbow-related problems. The other LU points are located on the forearm or wrist, not at the elbow crease near the biceps tendon, so they don’t fit this description.
