+{Which of the following options would be the earliest invasive diagnostic technique carried out clinically:
+|type="()"}
+- &nbsp; ultrasound
+|| Incorrect! {{Ultrasound}} is not an invasive diagnostic technique, while the {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12.
+- &nbsp; amniocentesis
+|| Incorrect! {{Amniocentesis}} is a prenatal diagnostic test carried out mainly between {{GA}} week 14 to 18, the {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12.
++ &nbsp; chorionic villus sampling
+|| Correct! {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12. Amniocentesis is a later test carried out mainly between {{GA}} week 14 to 18.
+- &nbsp; none of the above
+|| Incorrect! {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12.
-{Which of the following is the most correct statement about the primitive streak:
+{Which placental parameter is measured by ultrasound at the mid-portion from the chorionic plate to the basilar plate.
 |type="()"}
-- &nbsp; extends from the primitive node to the parachordal plate
+- &nbsp; placental diameter
-- &nbsp; is a primary inducer during organogenesis
+|| Incorrect! placental diameter is measured in the transverse section by calculating the maximum dimensions of the chorionic surface.
-+ &nbsp; is a site of migration of epiblast cells to form the mesoderm
++ &nbsp; placental thickness
-|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
+|| Correct! Note that the placental thickness approximates in millimeters to the weeks of gestation.
-- &nbsp; persists as the parachordal plate
+- &nbsp; placental volume
-- &nbsp; all of the above are correct
+|| Incorrect! placental volume is measured by a range of different methods and calculations, more recently with three-dimensional ultrasound.
+- &nbsp; placenta position
+|| Incorrect! placental thickness is measured by ultrasound at the mid-portion from the chorionic plate to the basilar plate.
