A) chorio allantoic membrane and yolk sac
B) amnion, chorion and yolk sac
C) chorio allantoic membrane and endometrium
D) allantois and endometrium
Correct Answer: C
Solution :
In rabbit, allantois comes in contact with chorion and their mesodermal layers fuse together and becomes highly vascular. Thus a compound layer is formed called Allanto- chorion or chorio-allantoic. Its chorionic villi invade the maternal uterine wall (endometrium) forming an allantoic placenta for absorbing nutrients.You need to login to perform this action.
