Initial visceral pain from appendicitis is referred to which region?

Explanation:
Pain from the early stages of appendicitis is referred to the area around the umbilicus. This happens because the appendix is a midgut structure and its visceral afferents travel with sympathetic fibers to the T10 spinal level. The brain interprets these signals as arising from the skin segment supplied by T10, which corresponds to the periumbilical region. As inflammation progresses and the parietal peritoneum becomes irritated, the pain becomes sharp and localized to the right lower quadrant. So the initial referred pain is in the umbilical region.
