0

Hormone that stimulates milk secretion

Prolactin

1

Hormone that stimulates milk ejection

Oxytocin

2

Increasing levels of this hormone is responsible for the progression of parturition

Oxytocin

3

Hormone that makes glucose available for fetus

HPL

4

Source of estrogen and progesterone during last trimester of pregnancy

Placenta

5

Fetal organ that produces DHEA to be converted to estrogen

Adrenal cortex

6

Responsible for prevention of entry of more than one sperm in oocyte

Cortical reaction

7

Contact of sperm head and zona pellucida is made possible by this reaction

Acrosomal reaction

8

True or false.
Implantation of zygote involves infiltration of myometrium by synctiotrophoblasts.

False. Infiltration of myometrium does not occur only infiltration of endometrium.

9

This activates exocytosis of cortical granules

Ca signaling cascade

10

High levels of this hormone is responsible for morning sickness

hCG

11

Luteal placental shift happens on the _th week of pregnancy

8th week of pregnancy

12

Hormone Responsible for myometrial quiescence

Progesterone

13

Hormone Responsible for cervical rigidity

Progesterone

14

Hormone responsible for cervical ripening

Estrogen

15

Both hormones that stimulate breast growth and development

Progesterone and estrogen

16

Ovulation is suppressed when there is lactation because

Prolactin inhibits GnRH secretion which consequently inhibits LH and FSH secretion

17

Hormone that inhibits prolactin

Dopamine

18

Explains suppression of lactation during pregnancy

High progesterone and estrogen

19

Hormone that prevent luteolysis

hCG

20

Apposition occurs in the

Crypts

21

It is when the embryonic pole attaches to the uterine endometrium

Adhesion

22

Decidua secretes these factors which moderate activity of hydrologic enzymes. What are these factors?

Tissue inhibitors of metalloproteinases (TIMPs)
