Which of the following pairs of terms and description is mismatched?

A) Foramen ovale - ligamentum ovale
B) Ductus arteriosus - ligamentum arteriosus
C) Ductus venosus - ligamentum venosus
D) Umbilical vein - ligamentum teres of the liver
E) Umbilical arteries - cords of umbilical arteries

Ligamentum Ovale

Ligamentum Ovale, often considered a mistake or a non-existing term in human anatomy, should likely refer to ligamentum teres or another specific ligament, as the term itself is not standard.

Ligamentum Arteriosum

Remains of the ductus arteriosus.

Ligamentum Venosus

A fibrous remnant of the fetal ductus venosus that connected the umbilical vein to the inferior vena cava, becoming ligamentous after birth.

Final Answer :
A
Explanation :
The correct term that corresponds to the foramen ovale after it closes postnatally is the fossa ovalis, not the ligamentum ovale. The other options correctly match the fetal structure with its postnatal remnant.
