umbilicis

Umbilicis is a term that refers to the navel, also known as the belly button. It is a common anatomical feature found in most mammals, including humans. The umbilicus is the scar that remains after the umbilical cord is detached following birth. The umbilical cord is a vital organ that connects the developing fetus to the placenta, providing nourishment and oxygen.

The appearance of the umbilicus can vary significantly from person to person. It can be an "innie," where the scar tissue is recessed inward, or an "outie," where it protrudes outward. These variations are largely determined by genetics and the way the umbilical cord stump heals after birth. In most cases, the umbilicus is a non-functional remnant with no medical significance.

While generally harmless, the umbilicus can be a site for certain medical conditions. Infections can occur, particularly in newborns if the umbilical stump is not kept clean. In some individuals, a weakness in the abdominal wall near the navel can lead to an umbilical hernia, where abdominal contents protrude through the opening. Surgical repair is often necessary for larger or symptomatic umbilical hernias. The umbilicus can also be a site for skin conditions or minor irritations.
