Target is the pitautry gland

Question 6

This stimulates the pituatry gland and does makes 2 hormones

Answer 6

FSH male & female

ICSH = M
LH = F

Question 7

What does the release of hormones trigger

Answer 7

The onset of sperm production and menstrual cycle

Question 8

FSH AND ICSH produced by the pituatry gland travel where

Answer 8

In the blood stream to the testes

Question 9

FSH promotes sperm production where

Answer 9

Seminiferous tubules

Question 10

Then what does ICSH stimulate

Answer 10

The interstitial cells to produce the hormone testosterone

Question 11

What does the testosterone do

Answer 11

1. Stimulate sperm production in the seminiferous tubules
2. Activates the prostate gland and seminal vesicles to produce their secretions

Question 12

Negative feed back 🙂

Question 13

How does inhibition of secretion of FSH and ICSH from the pituitary gland

Answer 13

As the concentration of testosterone builds up in the bloodstream

Question 14

This leads to a decrease in Test obviously

Answer 14

Lol

Question 15

Then what happens

Answer 15

This triggers the pituatry gland to again produce FSH and ICSH and so on

Question 16

The menstrual cycle 🩸

Question 17

How long does the peroid take bruh

Answer 17

28 days prob

Question 18

Whats the first day called my guy

Answer 18

Blood flow

Question 19

When does ovulation occur then?

Answer 19

Day 14

Question 20

What are the 2 stages of the peroid

Answer 20

1. Follicular phase (1st half of the cycle)
2. The luteal phase (2nd half of the cycle)

Question 21

FSH phase 😔

Question 23

FSH is made where

Answer 23

Pituatry gland

Question 24

What does FSH do in the phase

Answer 24

•stimulates development and maturation of a follicle

•stimulates production of eostrigen by follicle

Question 25

Then Wtf does eostrogen do

Answer 25

•Stimulates proliferation of the endometrium preparing it for implantation

Question 26

Pt2 of the previous question Peak levels of oestrogen stimulate a surge in what

Answer 26

LH production

Question 27

What does the increase do

Answer 27

Affects the consistency of cervical mucus making it easily penetrated by sperm

Question 28

LH phase

Answer 28

Surge of LH triggers ovulation

Question 29

What is ovulation

Answer 29

Release of an egg from a follicle in an ovary and it occurs mid point of the period

Question 30

Luteal phase 🥲🫵🫵

Answer 30

Stimulates follicle to develop into corpus lutem •CL secrets proestrogen

Question 31

Progesterone (made by CL)

Answer 31

Promotes further development and increases vascularisation of the endometrium

Question 32

What does that STAGE DO

Answer 32

Prepares it for implantation if fertilisation occurs

Question 34

Negative feedback

Question 35

What causes negative feedback

Answer 35

High levels of oestrogen and progesterone levels

Question 36

Then what habits

Answer 36

The peak levels inhibit secretion of FSH and LH by the pituitary gland

Question 37

Then what

Answer 37

The concentrations of FSH and LH decrease preventing further follicles from developing

Question 38

Random bull crap

Answer 38

I

Question 39

If fertilisation doesn’t occur what happens

Answer 39

Lack of LH leads to degeneration of corpus lutem and therefor a decrease in progesterone levels leading to menstruation

Question 40

If fertilisation does

Answer 40

The corpus lutem does not degenerate progesterone remains high with levels
