	true
	false

3 Gamete differentiation occurs while diploid in

	oocytes
	spermatozoa

4 Which of the following is incorrect about the block to polyspermy

	occurs after fertilization
	occurs when meiosis II is completed
	occurs initially when sperm and oocyte membranes fuse
	occurs when cortical granules are released

5 Which of the following statements about the blastocyst is most correct

	the blastocyst forms from the 2 blastomere stage
	the blastocyst has a cavity lined with endoderm
	the blastocyst stage occurs after hatching from the zona pellucida
	the blastocyst has an embryoblast and trophoectoderm layer

6 Select the correct options below for the process of implantation

	is driven by the trophoblast layer
	occurs following adplantation
	can occur inside and outside the uterine body
	allows endocrine support of the corpus luteum

7 The extraembryonic coelom refers too

	amniotic cavity, yolk sac and chorionic cavity
	pericardial cavity, pleural cavity and peritoneal cavity
	blastocoel, somitocoel and lateral plate coelom
	maternal lacunae, uterine gland lumen, uterine body cavity

8 Which of the following statements is incorrect about the process of gastrulation

	gives rise to the trilaminar embryo
	involves cell migration from the epiblast layer
	extends from the primitive node to the buccopharyngeal membrane
	occurs at the region known as the primitive streak
	generates endoderm and then mesoderm layers

9 What are the two main early embryonic developmental roles of the notochord

	mechanical role in embryonic disc folding and signaling for tissue patterning
	formation of the nucleus pulposis and separating cloacal and buccopharyngeal membranes
	gastrulation and neuralation
