Homonym: navel (Belly)
The navel, commonly known as the belly button, is a small, central scar on the abdomen. It is the remnant of the umbilical cord, which connects a developing fetus to its mother during pregnancy. After birth, the umbilical cord is cut, leaving behind the navel as a permanent mark on the body.
The navel can vary in shape and size among individuals, and it serves no significant biological function in adults. However, it is often considered a point of interest in anatomy and can be associated with various cultural practices and beliefs, including those related to body image and aesthetics.
