What is FSH
|
Follicle stimulating hormone
|
|
|
What does FSH do
|
stimulates the development of follicles in the ovary and stimulates them to produce oestrogen
|
|
|
What does oestrogen do
|
causes the rebuilding of the uterus lining after menstruation
|
|
|
What is LH
|
leuteinising hormone
|
|
|
What does LH do
|
causes ovulation to occur and stimulates the ovary to produce progesterone
|
|
|
What does progesterone do
|
maintains the lining of the uterus in readiness to receive the fertilised egg and inhibits the production of FSH
|
|
|
What is released from the pituitary gland
|
FSH and LH
|
|
|
What is released by the ovaries
|
Oestrogen and Progesterone
|
|
|
Where exactly is progesterone released from
|
corpus luteum
|
|
|
What does oestrogen inhibit and stimulate
|
low amounts inhibit LH and FSH, but high amounts stimulate LH and FSH
|
|
|
What does FSH stimulate
|
Oestrogen
|
|
|
what does LH stimulate
|
Progesterone
|
|
|
What does progesterone inhibit
|
inhibits LH and FSH
|
|
|
What happens on day 1
|
the pituitary gland releases FSH into the blood which stimulates follicles in the ovary to grow and mature
|
|
|
What does the follicle do once released
|
secretes oestrogen into the blood causing uterus lining to build up again and inhibits FSH and LH
|
|
|
as the follicle grows what happens
|
more oestrogen is released and it reaches a critical point where it stimulates the release of FSH and LH
|
|
|
what happens when there is a surge in FSH and LH
|
LH causes the ovary to release an egg, this is ovulation
|
|
|
what happens after ovulation
|
LH stimulates the empty follicle to develop into a corpus leteum which secretes progesterone
|
|
|
what is an example of negative feedback
|
when low levels of oestrogen inhibit FSH and LH
|
