Which point is located in the centre of the tip of the middle finger; alternatively near the radial side of the middle finger, at the junction of lines drawn along the radial border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail?

Which point is located in the centre of the tip of the middle finger; alternatively near the radial side of the middle finger, at the junction of lines drawn along the radial border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail?

• A. PC 7
• B. SJ 2
• C. PC 3
• D. PC 9

Answer: (D)

The point being tested is the endpoint of the Pericardium channel, located at the fingertip. It sits at the center of the tip of the middle finger, described as either the center of the nail tip or just to the radial side near the nail base, about 0.1 cun from the nail corner. This precise fingertip location is what distinguishes it from other points, which are found on the wrist, the elbow, or on other fingers. The center-of-the-tip position matches the described landmark exactly, making it the correct choice.
