{Which of the following is the most correct statement about the primitive streak:
{During late pregnancy, which of the following layers of placental membrane is in direct contact with maternal blood?
|type="()"}
|type="()"}
- &nbsp; extends from the primitive node to the parachordal plate
- &nbsp; the cytotrophoblastic shell
- &nbsp; is a primary inducer during organogenesis
|| Incorrect! Only the {{syncytiotrophoblast}} layer is in direct contact with maternal blood.
+ &nbsp; is a site of migration of epiblast cells to form the mesoderm
+ &nbsp; the syncytiotrophoblast
|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
|| Correct! The {{syncytiotrophoblast}} layer is in direct contact with maternal blood.
- &nbsp; persists as the parachordal plate
- &nbsp; the extraembryonic mesoderm
- &nbsp; all of the above are correct
|| Incorrect! Only the {{syncytiotrophoblast}} layer is in direct contact with maternal blood.
- &nbsp; the intraembryonic mesoderm
|| Incorrect! Only the {{syncytiotrophoblast}} layer is in direct contact with maternal blood.
- &nbsp; the endothelium of placental blood vessels
|| Incorrect! Only the {{syncytiotrophoblast}} layer is in direct contact with maternal blood.


{Which one of the following statements about the maternal decidual reaction is '''most''' correct.
|type="()"}
- &nbsp; the maternal decidual reaction commences at the site of implantation
|| Correct! But not the most correct answer. All of the statements correctly refer to the maternal decidual reaction.
- &nbsp; the maternal decidual reaction protects the uterine wall from over implantation
|| Correct! But not the most correct answer. All of the statements correctly refer to the maternal decidual reaction.
- &nbsp; the maternal decidual reaction spreads through the entire uterus
|| Correct! But not the most correct answer. All of the statements correctly refer to the maternal decidual reaction.
- &nbsp; the maternal decidual reaction involves the uterine stromal cells
|| Correct! But not the most correct answer. All of the statements correctly refer to the maternal decidual reaction.
+ &nbsp; all of the above refer to the maternal decidual reaction
|| Correct! All of the statements correctly refer to the maternal decidual reaction.
{How is the uterine cavity lost?
|type="()"}
- &nbsp; decidua basalis and decidua capsularis fuse
- &nbsp; decidua basalis and decidua parietalis fuse
+ &nbsp; decidua capsularis and decidua parietalis fuse
|| Correct! The decidua capsularis and decidua parietalis eventually fuse as the fetus grows within the wall of the uterus and the uterine cavity is then lost.
- &nbsp; all decidual layers fuse
- &nbsp; none of the above
{Which maternal arteries are remodelled by trophoblast cells?
|type="()"}
- &nbsp;internal iliac artery
|| Incorrect! internal iliac artery
- &nbsp; uterine artery
|| Incorrect! uterine artery form anterior division of the internal iliac artery, spiral arteries are invaded by trophoblast cells that remodel them  into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]]
- &nbsp; arcuate arteries
|| Incorrect! arcuate arteries, also called helicine arterioles are not remodelled, spiral arteries are invaded by trophoblast cells that remodel them  into highly dilated vessels.  See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]]
- &nbsp; helicine arterioles
|| Incorrect! helicine arterioles, also called arcuate arteries are not remodelled, spiral arteries are invaded by trophoblast cells that remodel them  into highly dilated vessels.  See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]]
- &nbsp; radial arteries
|| Incorrect! radial arteries span the myometrium, spiral arteries are invaded by trophoblast cells that remodel them  into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]]
+ &nbsp; spiral arteries 
|| Correct! spiral arteries are invaded by trophoblast cells that remodel them  into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]]
{Which of the following terms best describes the form of human placental organisation/classification?
|type="()"}
+ &nbsp; Haemochorial
|| Correct! In human placenta where the chorion comes in direct contact with maternal blood.
- &nbsp; Endotheliochorial
|| Incorrect! Endotheliochorial placenta is when maternal endometrial blood vessels are bare to their endothelium and these comes in contact with the chorion ({{dog}}, {{cat}}). The human placenta is haemochorial where the chorion comes in direct contact with maternal blood.
- &nbsp; Epitheliochorial
|| Incorrect! Epitheliochorial placenta is when maternal epithelium of the uterus comes in contact with the chorion, considered as primitive ({{pig}}, {{cow}}). The human placenta is haemochorial where the chorion comes in direct contact with maternal blood.
