(345 cards)
1
Q
What is the hypothalamic pituitary gonadal axis ?
A
The hypothalamus releases GnRH which stimulates the anterior pituitary to produce LH and FSH.
These stimulate the development of follicles in the ovaries. The theca granulosa cells secrete oestrogen which has a negative feedback effect on the hypothalamus and anterior pituitary.
2
Q
What is oestrogen ?
A
A steroid sex hormone produces by the ovaries in response to LH and FSH. It acts to promote female secondary sexual characteristics.
3
Q
What does oestrogen stimulate ?
A
Breast tissue development
Growth and development of the female sex organs at puberty
Blood vessel development in the uterus
Development of the endometrium.
4
Q
What is progesterone ?
A
A steroid sex hormone produced by the corpus luteum after ovulation.
When pregnancy occurs progesterone is mainly produced by the placenta.
5
Q
What are the main functions of progesterone ?
A
Thickens and maintains the endometrium
Thickens the cervical mucus
Increases the body temperature
6
Q

A
The moment of ovulation to the start of menstruation
11
Q
What hormone spikes before ovulation ?
A

12
Q
What does the corpus luteum secrete ?
A
