Here are a few simple questions that relate to your introduction to embryology lecture and practical.


Take the Quiz

  

1 I already really know all I need to know about embryology.

true
false

2 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

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

true
false

4 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

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

Estrogen
Progesterone
human Chorionic Somatommotropin
human Chorionic Gonadotrophin
human Chorionic Corticotropin

6 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

7 The second and third trimesters cover the fetal period of development.

true
false

8 Which of these statements about environmentally derived abnormal development is incorrect:

bacterial and viral infections can sometimes not affect development
a specific environmental insult will result in a specific abnormal development outcome
the first trimester is the most sensitive period to environmental insults
some prescription drugs can lead to abnormal development outcomes
