Which Heart point is 0.5 cun proximal to HT 7 on the radial side?

• A. HT 4
• B. HT 6
• C. HT 7
• D. HT 5

Answer: (B)

The important idea is how points along the Heart channel are spaced near the wrist. HT 7 is located at the wrist crease on the radial side of the flexor carpi ulnaris tendon. If you move 0.5 cun toward the elbow along the same tendon line (keeping to the radial side), you reach the next point, HT 6. So HT 6 is the closest Heart-point neighbor to HT 7 in the proximal direction on the radial side. The other options aren’t this proximal neighbor along that same line, so they don’t fit the given measurement.
