Not to be confused with Medial umbilical ligament.
In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall.[1] It is covered by the median umbilical fold.[citation needed]
The median umbilical ligament represents the remnant of the fetal urachus.[1][2] It extends from the apex of the bladder to the umbilicus, on the deep surface of the anterior abdominal wall.[2]
The median umbilical ligament represents one of the five ligaments of the internal anterior abdominal wall inferior to the umbilicus; laterally on either side of it are one medial umbilical ligament and finally one lateral umbilical ligament.[1]
