The term 'Omphalus' is a synonym for the word 'UMBILICUS', which refers to the navel or belly button. It is a small, circular scar on the abdomen that marks the spot where the umbilical cord was attached during pregnancy. The umbilical cord is a tube-like structure that connects the fetus to the placenta and provides nutrients and oxygen to the developing baby. The omphalus is a reminder of the connection between mother and child.
