which of the following decidua layer forms a partition between developing embryo and lumen at uterus?

Options

A. Decidua basalis
B. Decidua parietalis
C. Decidua capsularis
D. Contra deciduate

Answer

C

Explanation

The modified portion of endometrium of uterus upon implantation is called decidua. It sheds when foctus is delivered. Decidua basalis is part underlying the chorionic vill and overlying myometrium. Decidua parietalis (=Decidua vera) is the part that lines the uterus at places other than the site of attachment of embryo. 'Contra-deciduate' is that animal in which even the foetal part of placenta is retained and gets absorbed to provide nourishment. Example, Talpa (male).
