Which embryonic structure gives rise to median umbilical ligament? and medial umbilical ligament?
Good point to distinguish these two. I always get the 2 mixed up, so if anyone has an easy way to remember, please share![]()
Median umbilical ligament =The fibrous remnant of the urachus that joined the fetal bladder to the umbilicus. The median umbilical ligament passes from the deep aspect of umbilicus vertically to the apex of the urinary bladder.
Medial umbilical ligament =obliterated umbilical arteries; the obliterated parts of the fetal umbilical arteries. The 2 medial umbilical ligaments ascend obliquely from lateral pelvis walls to the umbilicus.
MNEUMONIC: I - O - U
From lateral to medial:
lateral umbilical ligament: Inferior epigastric vessels
medial unbilical ligament: Obliterated umbilical artery
median umbilical ligament: Urachus
Great, that is it!!!
