1

By the time the woman misses her first period, how many weeks is she into gestation?

two weeks

2

In how many weeks will the embryo transform into a fetus

end of week 8

3

When does morning sickness normally occur?

in the first trimester

4

Why are maternal adaptations required for pregnancy

to maintain uteroplacental perfusion and fetal demands

5

Which part of the blastocyst 1) invades 2) becomes the fetus

1) trophoblast
2) inner cell mass

6

Which two layers surround the amniotic fluid?

amnion and chorion

7

Are GIT and renal systems active in a fetus?

Yes, it is active from 12 weeks onward. They contribute to the amniotic fluid

8

T/F Amniotic fluid transports most of the fetus's waste product

False, the umbilical cord excretes most of the waste

9

What is the function of hCG

extends the lifespan of CL

10

What is the function of human placental lactogen

Breast development and metabolic effects

11

T/F Monozygotic twins come from the same fertilised ovum

True, hence they are identical (same sex). The ovum divides and implants to two sites

12

How is parturition initiated?

Breaking of the placenta

13

T/F Progesterone suppress uterine contraction

True

14

What is the action of oxytocin during parturition

causes uterine contraction, and cause the placenta to release prostaglandin for further contraction

15

T/F Oxytocin and protaglandins both work on a positive feedback loop

True

16

What's the advantage of having unfused skull bones on baby when it's getting delivered

So the bones can slide on top of each other, compress the skull so the baby can make through the birth canal

17

Which hormones lead to breast gland development during pregnancy

oestrogen, growth hormone and cortisol

18

Which hormone converts and ducts to secretory epithelium during pregnancy

progesterone

19

Which hormone blocks the production of prolactin?

prolactin-inhibiting hormone

20

After birth, how is lactation triggered?

both high level prolactin and low level oestrogen are required

21

While prolactin stimulates milk production, which hormone is responsible for milk ejection

Oxytocin

22

What is Frank diabetes

a pre-diabetic state

23

What is the definition of "preterm labour"

labour before 37 weeks gestation

24

What are the presenting symptoms of pre-eclampsia

high maternal blood pressure, proteinuria, generalised oedema

25

What's the treatment of pre-eclampsia

deliver the placenta and trophoblast so mother can recover

26

T/F Fetal growth is dependent on growth hormone

False, it's dependent on IGFs, thyroid hormones and insulin

27

T/F Glucocorticoids inhibit fetal growth

True

28

What's the difference between fetal growth restriction and being born premature

Premature = organ systems have not yet formed

FGR = organ systems have developed

29

T/F Accelerated growth is a good way to compensate for fetal growth deficiency

False, babies should not grow beyond the normal trajectory in order to prevent diseases

Just drink mother's milk. It's programmed to be what the baby needs
