Anatomy and Physiology of the Umbilicus

Abstract

The umbilicus embryologically represents the neck of the bottle, which contains the umbilical vessels and structures related to the digestive and urinary systems. After the fall of the umbilical stump a few days after birth, its scarred tissue remains as the belly button, which is considered a mirror of the abdomen and should be carefully checked, particularly for newborns. A basic understanding of its anatomy and embryology is essential to identify and manage its disorders. Investigating the abnormal conditions at the umbilicus is crucial, because corrective surgical interventions may be required and conducted as soon as possible.
