Question 10

Answer 10

Question 11

Answer 11

Question 12

Function GnRH?
Where released?

Answer 12

Posterior pituitary
Induce secretion FSH and LH from anterior pituitary

Question 13

Function FSH? (3)

Answer 13

Stimulate development follicles
Increase oestrogen secretion
Increase inhibin secretion from granulosa cells

Question 14

What synthesises LH and FSH?

Answer 14

Anterior pituitary gonadotrophs

Question 15

Function LH?

Answer 15

Stimulate theca cells produce androgens- converted oestrogen by granulosa- thicken endometrium
Stimulate ovulation
Conversion Graafian follicle into coprus luteum- produces progesterone

Question 16

What stimulates ovulation?

Answer 16

Surge LH

Question 17

What do theca cells produce?

Answer 17

Androgens

Question 18

What does Graafian follicle turn into?

Answer 18

Corpus luteum

Question 19

Define proliferative phase?

Answer 19

6-14
Growth ovarian follicle

Question 20

Define luteal phase?

Answer 20

16-28
Endometrium thickens

Question 21

When is ovulation?

Answer 21

Day 14
Lack progesterone
Shet endometrium

Question 22

State diff phases?

Answer 22

Proliferative-6-14- growth ovarian follicles
Ovulation- 14
Luteal- 16-28- endometrium thickens
Day 28/1- endometrium discarded

Question 23

Is mucus acid or alkaline?

Answer 23

Alkaline

Question 24

Explain process fertilisation?

Answer 24

0- Fertilisation- sperm and egg fuse and form zygote
1- zygote start travel fallopian tube
2- cleavage- first mitotic division
3- second mitotic division
4- compaction- third mitotic division- 16 cell morula
5-6- Morula differentiate to blastocyst
Blastocyst- outer trophoblast, blastocyst cavity
5-6- Zona pellucida thins and cavity expands
7- hatching- blastocyst implants into endometrium

Question 25

What is first, second and third mitotic division called?

Answer 25

Day 2- cleavage
Day 3- second
Day 4- compaction

Question 26

What does compaction form?

Answer 26

Morula

Question 27

How many cells in morula?

Answer 27

16

Question 28

What comes first morula or blastocyst?

Answer 28

Morula- 16
Blastocyst

Question 29

What is structure blastocyst?

Answer 29

Outer trophoblast
Blastocyst cavity

Question 30

Label
What is it

Answer 30

Blastocyst

Question 31

Function zona pellucida?

Answer 31

Responsible for species-restricted binding of sperm to unfertilized eggs
Preventing sperm from binding to fertilized eggs

Question 32

Name 2 types contraception?

Answer 32

Combined oral contraceptive pill
Progesterone only pill

Question 33

How does combined oral contraceptive pill work?

Answer 33

Surpress FSH and LH
Low FSH- inhibit follicular development- prevent increase oestrogen
Progesterone causes cervical mucous thicken
No implantation
Decreased production glycogen blastocyst survive

Question 34

How does progesterone only pill work?

Answer 34

Thicken mucous continuously
Take continuous 28 days
Inhibit ovulation
Varying degrees follicular development dependent dosage

Question 35

What does implantable rod or IUD do?

Answer 35

Release progesterone steady rate
