It contains the urachus, which is an embryonic remnant resulting from involution of the allantoic duct that connects the fetal urinary bladder to the umbilicus.
The median umbilical ligament is an unpaired ligamentous structure in human anatomy . It is covered by the median umbilical fold.
It extends from the apex of the urinary bladder to the umbilicus, on the deep surface of the anterior abdominal wall.

The median umbilical ligament may be used as a landmark for surgeons who are performing laparoscopy, such as laparoscopic inguinal hernia repair.
