Which point is located between the second and third metacarpal bones, proximal to the MCP joint, on the radial side of the third metacarpal?

Which point is located between the second and third metacarpal bones, proximal to the MCP joint, on the radial side of the third metacarpal?

• A. SJ 1
• B. PC 8
• C. PC 9
• D. PC 7

Answer: (B)

The point being tested is the exact location of a Pericardium point in the palm. The correct spot is the center of the palm, between the 2nd and 3rd metacarpal bones, located proximal to the MCP joints and on the radial (thumb) side of the 3rd metacarpal. This is the Laogong point, PC-8. It sits right in the depression in the center of the palm between those two metacarpals, making it the only choice that matches the described location. The other options lie in different regions: one is not in that intermetacarpal palm area, another is at the fingertip, and another is at the wrist, so they don’t fit the described location.
