umbilical cord - Cultural Definition
A ropelike structure that connects a developing embryo or fetus to the placenta. The umbilical cord contains the blood vessels that supply the embryo or fetus with nutrients and remove waste products. Connected to the abdomen of the embryo or fetus, the umbilical cord is cut at birth, leaving a small depression — the navel, or “belly button.”
