Default e

umbilical vein, arteries & urachus are derivatives of alantois. they themselves give rise to:
vein - ligamentum teres,
arteries - medial umbilical ligaments,
urachus- median ligament.

Default None of the above ;-)

As i remember
umbilical vein - ligamentum teres (no such option)
umbilical artery- medial umblical ligament.

I think if i remember correct-
median umbilical ligament is related to allantois.

Yes, as all of them answered.....none of these is corrected(with respecitvely considering in question)


ya.....both umbilical A. and V. are derived from allantois and after birth derived to medial umbilical ligament and ligamentum teres respectively

the remaining derivative from allantois(urachus) derives into median umbilical ligament
