+{During implantation the blastocyst:
+|type="()"}
+- &nbsp; usually implants in the posterior wall of the body of the uterus
+|| Correct! But not the most correct answer.
+- &nbsp; releases substances that cause local changes in the endometrial tissue
+|| Correct! But not the most correct answer.
+- &nbsp; attaches itself to endometrium at its embryonic pole
+|| Correct! But not the most correct answer.
++ &nbsp; all of the above are correct
+|| Correct! All of the above are correct.
+{During week 2 ({{GA}} week 4) the blastocyst trophectoderm (trophoblast) layer initially differentiates into two layers the:
+|type="()"}
+- &nbsp; hypoblast and trophoblast
+|| Incorrect! During week 2 ({{GA}} week 4) during early {{implantation}} the {{blastocyst}} trophectoderm ({{trophoblast}}) layer initially differentiates into the '''{{syncytiotrophoblast}}''' and '''{{cytotrophoblast}}''' layers.
+- &nbsp; epiblast and primitive yolk sac
+|| Incorrect! During week 2 ({{GA}} week 4) during early {{implantation}} the {{blastocyst}} trophectoderm ({{trophoblast}}) layer initially differentiates into the '''{{syncytiotrophoblast}}''' and '''{{cytotrophoblast}}''' layers.
++ &nbsp; syncytiotrophoblast and cytotrophoblast
+|| Correct! During week 2 ({{GA}} week 4) during early {{implantation}} the {{blastocyst}} trophectoderm ({{trophoblast}}) layer initially differentiates into the '''{{syncytiotrophoblast}}''' and '''{{cytotrophoblast}}''' layers.
+- &nbsp; hypoblast and epiblast
+|| Incorrect! During week 2 ({{GA}} week 4) during early {{implantation}} the {{blastocyst}} trophectoderm ({{trophoblast}}) layer initially differentiates into the '''{{syncytiotrophoblast}}''' and '''{{cytotrophoblast}}''' layers.

+{The intra-embryonic coelom transiently connects to the extra-embryonic coelom.
+|type="()"}
+- &nbsp; false
++ &nbsp; true
+|| Correct! During early development the intra-embryonic coelom transiently connects to the extra-embryonic coelom at the edge of the embryonic plate.
-{Which of the following is the most correct statement about the primitive streak:
+{In humans the most common site of implantation is:
 |type="()"}
-- &nbsp; extends from the primitive node to the parachordal plate
+- &nbsp; uterine tube
-- &nbsp; is a primary inducer during organogenesis
+|| Incorrect! This is a site of {{ectopic implantation}} associated with {{tubal pregnancy}}, but not the most common which is the posterior wall of the uterus.
-+ &nbsp; is a site of migration of epiblast cells to form the mesoderm
+- &nbsp; cervix
-|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
+|| Incorrect! This is a site of implantation associated with {{placenta previa}}, but not the most common which is the posterior wall.
-- &nbsp; persists as the parachordal plate
+- &nbsp; lateral wall of uterus
-- &nbsp; all of the above are correct
+|| Incorrect! This is a site of implantation, but not the most common which is the posterior wall.
++ &nbsp; posterior wall of uterus
+|| Correct!
+- &nbsp; anterior wall of uterus
+|| Incorrect! This is a site of implantation, but not the most common which is the posterior wall.
+{Which of the following structures are considered extra-embryonic coeloms?
+|type="[]"}
+- &nbsp; peritoneal sac
+|| Incorrect! The peritoneal cavity is an intra-embryonic coelom. The {{amniotic sac}}, {{chorionic sac}} and {{yolk sac}} are the three extra-embryonic coeloms.
++ &nbsp; yolk sac
+|| Correct! The {{yolk sac}}, {{chorionic sac}} and {{amniotic sac}} are the three extra-embryonic coeloms.
+- &nbsp; allantois
++ &nbsp; chorionic sac
+|| Correct! The {{chorionic sac}}, {{yolk sac}} and {{amniotic sac}} are the three extra-embryonic coeloms.
++ &nbsp; amniotic sac
+|| Correct! The {{amniotic sac}}, {{chorionic sac}} and {{yolk sac}} are the three extra-embryonic coeloms.
+- &nbsp; pericardial sac
+|| Incorrect! The pericardial cavity is an intra-embryonic coelom. The {{amniotic sac}}, {{chorionic sac}} and {{yolk sac}} are the three extra-embryonic coeloms.
