| Name = Median umbilical ligament | Latin = Ligamentum umbilicale medianum, ligamentum suspensorium vesicae urinariae | Image = Gray1036.png | Caption = Posterior view of the anterior abdominal wall in its lower half. The peritoneum is in place, and the various cords are shining through. Median umbilical ligament isn't labeled, but it is located just underneath the median umbilical fold, seen in the center of the diagram | Image2 = | Caption2 = | System = | From = Apex of urinary bladder | To = umbilicus }} The median umbilical ligament is a structure in human anatomy. It is a shrivelled piece of tissue that represents the remnant of the embryonic urachus. It extends from the apex of the bladder to the umbilicus, on the deep surface of the anterior abdominal wall. It is unpaired. It is covered by the median umbilical fold. Lateral to this structure are the medial umbilical ligament (which is a different structure, not to be confused) and the lateral umbilical ligament. SignificanceIt may be used as a landmark for surgeons who are performing laparoscopy, such as laparoscopic inguinal hernia repair. Other than this, it has no function in a born human and may be cut or removed with impunity. It contains the urachus, which is the obliterated form of the allantois. The allantois forms a communication between the cloaca (terminal part of hindgut) and the outside world during embryonic development. ReferencesExternal links
