What type of pain arises from the abdominal organs?

• A. Parietal pain
• B. Visceral pain
• C. Somatic pain
• D. Referred pain

Answer: (B)

Pain from abdominal organs is visceral pain. It comes from stimulation of the visceral afferent fibers that supply the organs, such as when a hollow organ distends, becomes inflamed, or is ischemic. These fibers travel with autonomic nerves to the spinal cord, and because several organs share similar pathways, the brain can’t pinpoint the exact source easily. The result is a diffuse, dull, or cramp-like sensation felt in a broad area, often around the midline or periumbilical region. A familiar example is appendicitis, where early visceral pain around the navel becomes sharper and more localized only after irritation of the parietal peritoneum. This contrasts with parietal pain (sharp and well localized from the peritoneum), somatic pain (from body walls like skin or muscles), and referred pain (pain felt at a distant site due to shared neural pathways).
