Here are a few simple questions that relate to your introduction to embryology lecture and practical, this page is not a part of today's Practical class.

You should try in your own time after completing the Practical today.

Take the Quiz

1 Which of the following statements is most correct about the human menstrual cycle.

	The menstrual cycle in all women is a 28 day reproductive cycle
	Ovulation always occurs at the midpoint of the menstrual cycle
	The menstrual cycle's main function is to regularly replace the lining of the uterus
	A high body temperature indicates ovulation is occurring
	The menstrual cycle is an endocrine cycle regulating reproductive physiological changes

2 Most pregnancies can be detected by pregnancy tests soon after fertilization.

	true
	false

3 Which of the following statements is correct about the zona pellucida:

	surrounds the oocyte in the ovary
	protects oocyte in the uterine tube
	is a specialized extracellular matrix
	is important for fertilization
	all of the above

4 Pregnancy tests generally are based upon the detection in maternal urine of:

	Estrogen
	Progesterone
	human Chorionic Somatommotropin
	human Chorionic Gonadotrophin
	human Chorionic Corticotropin

5 The most correct sequence of early development following fertilization is:

	zygote, blastomeres, morula, blastocyst
	oocyte, zygote, morula, blastocyst
	zygote, conceptus, blastocyst
	polar bodies, zygote, conceptus, blastocyst

6 Which process in the third week of development converts the embryonic disc into the trilaminar embryo.

	placentation
	gastrulation
	neuralation
	somitogenesis
	embryonic disc folding

7 Which of the following statements about Figure 1 (shown below) is most correct:

	figure 1 shows a normal female karyotype
	figure 1 shows all human chromosomes
	figure 1 shows a metaphase spread of a human genome
	figure 1 shows an abnormality of mitosis
