HT-1 is located 3 cun proximal to the medial end of the transverse cubital crease on the line connecting which two points?

• A. Jíquán HE-1 and Shàohǎi HE-3
• B. Qūzé P-3 and Shàohǎi HE-3
• C. Jíquán HE-1 and Qūzé P-3
• D. Shàohǎi HE-3 and Qūzé P-3

Answer: (A)

The main idea is the path of the Heart channel along the inner upper limb. HT-1 lies on the Heart channel, on the line that runs from Jíquán (HT-1) in the axilla to Shàohǎi (HT-3) near the elbow. Being 3 cun proximal to the medial end of the transverse cubital crease places HT-1 on that same line between those two points. So the correct line is the one connecting Jíquán and Shàohǎi. This line defines the Heart channel’s trajectory on the upper arm, which is why the location is described this way.
