Visceral pain originates from which tissue?

• A. The Skin
• B. Muscles
• C. Viscera (Lining Of Chest/Abdominal Organs)
• D. Bones

Answer: (C)

Visceral pain comes from the internal organs and their lining of the chest and abdominal cavities. The receptors in these tissues respond to stretch, distension, ischemia, or inflammation, and the signals travel with autonomic nerves to the spinal cord. This wiring yields a dull, poorly localized ache that can be felt in a midline or referred area rather than as a sharp, pinpoint pain. In contrast, skin, muscles, and bones have somatic nerves that provide sharp, well-localized pain. So the tissue responsible for visceral pain is the viscera and their lining, not the skin, muscles, or bones, with pain often described as diffuse and sometimes referred to other areas served by the same spinal segments.
