The navel, also known as the belly button, is a small depression located on the abdomen. The anatomy of the navel includes the following parts:
Umbilicus: This is the visible part of the navel, which is the small depression on the surface of the skin.
Umbilical cord: During pregnancy, the umbilical cord connects the baby to the placenta and allows for the transfer of nutrients and oxygen from the mother to the developing fetus.
Umbilical ring: This is the small opening in the abdominal muscles where the umbilical cord was attached.
Umbilical stalk: This is the small piece of tissue that connects the umbilicus to the umbilical ring.
Umbilical granuloma: This is a small, benign growth that can occur in the navel, usually after the umbilical cord has been cut at birth.
Scar tissue: The navel area may contain scar tissue, which results from the cutting of the umbilical cord.
