Description:
Inflamed appendix and pain route. This image depicts the anatomical background of the classical pain presentation of (early) appendicitis. The pain signal from the appendix follows the indicated route to arrive at a certain level of the spinal cord. Sensory information from the abdominal wall in the umbilical area arrives at the same level in the spinal cord. The origin of the pain signal then cannot be distinguished anymore, leading to so called 'referred pain' experienced in the abdominal wall around the umbilicus.
