The navel, also known as the belly button or umbilicus, is a small depression in the abdominal wall at the point of attachment of the umbilical cord. It is a scar that forms after the detachment of the umbilical cord after birth. The umbilical cord is a soft, bendable tube that carried nutrients, vitamins, and minerals from the mother to the baby when the baby was in the womb. After the baby is born, the umbilical cord is cut, and a tiny stump is left. When this stump falls off after a few weeks, the baby is left with his or her very own belly button. The navel is unique to each individual due to it being a scar, and various general forms have been classified by medical practitioners. The navel is used to visually separate the abdomen into quadrants. The navel has no function after birth and is simply a remnant of the umbilical cord that connected the baby to the mother. However, the navel can still have its uses, such as being a recommended site of incision for various surgeries, including transgastric appendicectomy, gall bladder surgery, and the umbilicoplasty procedure itself.
