Referred pain is the perception of visceral sensations in which location?

• A. In a distant skin region
• B. In the organ itself
• C. In the skin region corresponding to the organ's spinal segment
• D. In the muscle

Answer: (C)

Referred pain happens because visceral (organ) signals and somatic (skin) signals share the same spinal cord pathways. Visceral afferents travel with autonomic nerves and enter the spinal cord at particular segments. The brain, expecting pain to come from the skin, maps these signals to the skin region served by those same spinal segments. That skin area is where the pain is felt, not in the organ itself or a distant muscle. So the perception occurs in the skin region corresponding to the organ’s spinal segment.
