-{The decidua that takes part in the formation of the maternal component of the placenta is:
+{Which of the following best describes the term "ectomesenchyme":
 |type="()"}
-+ the decidua basalis
+- ectoderm derived from mesoderm
-- the decidua capsularis
+- epithelium derived from connective tissue
-- the decidua parietalis
+- sensory placodal induction by mesoderm
-- the villous chorion
++ connective tissue derived from neural crest
-- the smooth chorion
+|| The term "ectomesenchyme" refers to {{neural crest}} ('''ecto'''derm) forming connective tissue structures ('''mesenchyme''') in the head.
-|| The decidua basalis forms the maternal component of the placenta.
+- none of the above is correct
-{The usual site of ectopic pregnancy is the:
-|type="()"}
-- abdominal cavity
-+ uterine tube
-- ovary
-- cervix of the uterus
-- external surface of the uterus
-|| The most common site for an {{ectopic pregnancy}} is the uterine tube (tubal pregnancy).
-{Which of the following statements is most correct:
+{Which of the following best describes the buccopharyngeal membrane structure:
 |type="()"}
-- A partial hydatidiform mole is a conceptus with only paternal chromosomes.
+- a ventral surface indentation in the early embryo head
-+ A complete hydatidiform mole is a conceptus with only paternal chromosomes.
+- endoderm layer of the foregut
-- Triploidy is generated by an oocyte not completing meiosis and then fertilised by one sperm.
+- ectoderm layer of the epidermis
-- Hydatidiform moles are easily identified as they do not produce hCG.
++ ectoderm and endoderm
-- Hydatidiform moles cannot be identified by ultrasound and require other diagnostic tests.
+|| The buccopharyngeal membrane ({{oral membrane}}) consists of {{ectoderm}} and {{endoderm}} together. Endoderm layer of the foregut
-|| A complete hydatidiform mole is a conceptus with only paternal chromosomes.
+ and ectoderm layer of the epidermis are partially correct. The ventral surface indentation in the early embryo head is the stomedeum, on the floor of which is located the {{buccopharyngeal membrane}}.
+- none of the above is correct
+|| The buccopharyngeal membrane ({{oral membrane}}) consists of {{ectoderm}} and {{endoderm}} together. Endoderm layer of the foregut
+ and ectoderm layer of the epidermis are partially correct. The ventral surface indentation in the early embryo head is the stomedeum, on the floor of which is located the {{buccopharyngeal membrane}}.
-{Which of the following statements about week two ({{GA}} week 4) of development are incorrect:
-|type="()"}
-- This is the period of implantation into the wall of the uterus.
-+ Pregnancy from blastocyst hatching after this week occur in 50% of births.
-- Implantation during this week can occur anywhere within the uterus body.
-- hCG from trophoblast cells enters the maternal blood stream through uterine blood vessels.
-- The inner cell mass now differentiates into two distinct cellular layers.
-|| Blastocysts that "hatch" from the zona pellucida after week 2 are unlikely to result in a pregnancy as the menstrual cycle will have commences menses of the next cycle.
