Question

Fetal membranes develop and surround the fetus: Where is the location for these two types of membranes?

1) Amnion: Inside the chorion
2) Amnion: Outside the chorion
3) Amnion: In the uterus
4) Amnion: In the fallopian tube
5) Chorion: Inside the amnion
6) Chorion: Outside the amnion
7) Chorion: In the uterus
8) Chorion: In the fallopian tube

Answer 1

The amnion, which is filled with protective fluid, develops inside the chorion, and both of these membranes are located in the uterus, where the chorion contributes to the formation of the placenta.

Step-by-step explanation:

The amnion is a membrane that surrounds and protects the embryo, creating an amniotic cavity filled with fluid. It develops inside another membrane called the chorion, which is itself one of the most external extra-embryonic membranes. The chorion forms from the trophoblast and extraembryonic mesoderm and is fundamental in the development of the placenta, as it helps form the fetal portion. The location of these membranes is as follows: The amnion is located inside the chorion (1), and the chorion is located outside the amnion (6) and in the uterus (7), as it becomes part of the placenta that connects the fetus with the maternal blood supply.
