Medial umbilical fold

Plica umbilicalis medialis

Definition

The medial umbilical ligament (or cord of umbilical artery, or obliterated umbilical artery) is a paired structure. It is on the deep surface of the anterior abdominal wall and represents the remnant of the umbilical arteries, which serves no purpose in humans after birth, except for the initial part that becomes the adult superior vesical artery.
The medial umbilical ligament arises from the anterior division of the internal iliac artery.
