Q

Oogenesis

A
  • at birth 500k oocytes present
  • at puberty each cycle gives rise to one ovum
  • 420 ova released per ovulation
17
Q

Ovarian cyle

A

maturation/release of ovum

18
Q

Uterine cycle

A

building up and shedding uterine lining

19
Q

Tropic Hormonal control

A

anterior pituitary gland
- GnRH release from hypothalamus triggers the release of FSH/LH

20
Q

Follicle stimulating hormone (FSH)

A
  • acts on the gonads
  • promotes the release of sex hormones
21
Q

Luteinizing hormone (LH)

A
  • act on the gonads
  • promotes gamate production/maturation
22
Q

Parturition

A

cervical stretch causing oxytocin release (+ feedback loop), causing more cervicle stretch/dilation and more oxytocin release
