2

Blood supply from ? aa, but anastomosis w branches of ? aa in the ? ligament

ovaries have ? ? covered by germinal epithelium. ? ? contains conn tissue and bl vessels. cortex contains ? and ? cells

ovarian aa, uterine aa, broad ligament

outer cortex
inner medulla
follicles and theca cells

3

oestrogen secr by ? cells in the growing ? and also by theca cells > rare ? ? ? from these cells

a few ? enlarge each month under influence of ? but only ? reaches ~ 20mm and ruptures in response to ? ? ? surge to release its ?

granulosa
follicle
oestr secr tumours

follicles
FSH
one
mid cycle LH surge
oocyte

4

after ? the collapsed follicle becomes the ? ? - this continues to produce ? and ? to support ? whilst awaiting ? and ?.

ovulation
