Which site of referred pain is listed for the small intestine?

• A. Stomach
• B. Small intestine
• C. Liver
• D. Kidney and ureter

Answer: (B)

Visceral pain is referred to the skin areas that share the same spinal cord segments as the organ’s afferent nerves. Midgut structures, like the small intestine, send visceral afferents primarily to T10–T11, so pain is typically felt around the umbilicus (the periumbilical region).

Because the small intestine is the midgut structure responsible for this referral pattern, the site listed for its referred pain corresponds to the small intestine itself in this context. The other options map to different organs with their own typical referral zones (stomach to upper abdomen/epigastric area, liver to right upper quadrant, kidneys/ureter to flank or groin), which is why the small intestine is the best match here.
