What do the ovaries produce?
eggs/ova
From what cells are ova derived from?
germline cells
By what process do ova arise
meiosis
How do germline cells divide into germline cells?
mitosis
What chromosome complement do gametes have?
haploid
What is the chromosome complement of germline cells?
diploid
What is the function of the uterus?
is the place where the foetus grows
What lining in the uterus provides favourable conditions for implantation?
the endometrium lining
What can happen in the fallopian tubes?
fertilisation
What is a developing ovum surrounded by?
a Graffian follicle
Give one major function of the Graffian follicle
protects the ovum whilst it develops
What hormone is secreted by the Graffian follicle?
oestrogen
What other hormone is stimulated by the release of oestrogen?
Lutenising Hormone (LH)
Give another function of oestrogen
repairs the endometrium after ovulation
What two hormones are secreted by the pituitary gland that control female fertility?
Follicle Stimulating Hormone (FSH) and Lutenising Hormone (LH)
Roughly, when is oetrogen released by the follicle during the menstrual cycle?
start/middle
Roughly, when is progesterone released during the menstrual cycle?
middle/end
FSH causes the follicle to…
develop
LH stimulates…
ovulation
What other process does LH bring about?
it causes the corpus luteum to develop after ovulation occurs
What pituitary hormone stimulates the production of oestrogen?
LH
What is the main function of progesterone?
development and vascularisation of the endometrium (ready to receive the blastocyst
Name the two stages of menstruation?
follicular and luteal phase
In what days of menstruation does the follicular phase occur?
1-14
In what days of menstruation does the luteal phase occur?
14-28
