Which point is on the palmar surface of the hand at the midpoints of the transverse creases of the proximal interphalangeal joints of the index, middle, ring and little fingers?

Which point is on the palmar surface of the hand at the midpoints of the transverse creases of the proximal interphalangeal joints of the index, middle, ring and little fingers?

• A. M-UE-9 SÌFÈNG
• B. M-UE-24 LUÒZHĚN
• C. N-UE-19 YĀOTÒNGXUÉ
• D. M-UE-22 BĀXIÉ

Answer: (A)

The exact landmark on the palm matters here: the midpoints of the transverse creases over the proximal interphalangeal joints of the index, middle, ring, and little fingers are the four points known as Si Feng. They sit on the palmar surface at those specific crease locations, one under each of those fingers, forming a clear, symmetrical group along the palm. So this option matches the described location precisely, making it the correct choice. The other named points sit at different hand landmarks or surfaces and do not align with those PIP crease midpoints, so they aren’t correct for this description.
