Here are a few simple Quiz questions that relate to Placental Villi from the practical.

~~++Questions to be updated++~~

{~~Which~~ of the ~~following~~ is ~~the most correct statement about the primitive streak~~:

{The stage of placental villi development where the core is initially solid mesoderm is:

-   ~~extends from~~ the ~~primitive node to the parachordal plate~~

-   is a primary ~~inducer during organogenesis~~

|| Incorrect! Only trophoblast layers at this stage. The secondary villi stage is when the primary villi have been invaded by extra-embryonic mesoderm.

+   ~~is a site of migration of epiblast cells to form the mesoderm~~

+   secondary villi

|| The ~~primitive streak~~ is ~~a site of migration of epiblast cells to form firstly endoderm and then~~ the mesoderm.

|| Correct! the secondary villi stage is when the primary villi have been invaded by extra-embryonic mesoderm.

-   ~~persists~~ as the ~~parachordal plate~~

- ~~  all of the above are correct~~

|| Incorrect! tertiary villi have formed blood vessels within the extra-embryonic mesoderm. The secondary villi stage is when the primary villi have been invaded by extra-embryonic mesoderm.

-   quaternary villi

|| Incorrect! There is no such stage as quaternary villi. The secondary villi stage is when the primary villi have been invaded by extra-embryonic mesoderm.

{The developing placenta arises from the:

+   decidua frondosum

|| Correct! The decidua frondosum "leafy" where the majority of villi are located is the location of the fetal component of the placenta.

-   decidua capsularis

|| Incorrect! The decidua capsularis, smooth chorion, is where villi are absent or not abundant. The decidua frondosum "leafy" where the majority of villi are located is the location of the fetal component of the placenta.

{The developing amniotic membrane later fuses with the:

+   chorionic membrane

-   maternal blood vessels

-   maternal uterine glands

-   none of the above
