Which point on the lower abdomen is 4 cun lateral to the midline?

• A. SP 12
• B. SP 13
• C. SP 11
• D. SP 10

Answer: (B)

The concept being tested is locating abdominal points by lateral distance from the midline using cun measurements. On the lower abdomen, there is a point that sits exactly 4 cun away from the midline along the Spleen channel. That point is SP13, which is why it’s the correct choice. To find it, identify the midline of the abdomen (the vertical line through the navel) and move about four finger widths laterally; the point there belongs to the Spleen channel and lies in the lower abdominal region. The other options lie at different positions relative to the midline or in different areas, so they do not match the 4-cun-lateral description.
