Navel
The Navel (pronounced: /ˈneɪvəl/), also known as the belly button or umbilicus, is a central scar on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel, and it is quite visible on the human body.
Etymology
The term "navel" comes from the Old English nafela, akin to the German Nabel, both derived from the Proto-Germanic *nabô. The word is related to the Latin umbilicus, the Greek omphalos, and the Sanskrit nabhi, all meaning "navel".
Anatomy
The navel marks the point where the umbilical cord was attached in the womb. After birth, the umbilical cord is cut, and the remaining stub falls off, leaving the navel. The appearance of the navel can vary significantly from person to person due to how the cord was cut and how the scar tissue forms.
