what are the organs of the female repro system
ovaries
uterine tubes (oviducts)
uterus (and cervix)
vagina
vulva
mammary glands
main functions of female repro system
production of oocytes--> ova
transport male and female gametes for fertilization
capacitation
accomodation and nourishment of embryo/fetus
parturition
secretion of hormones
what are the exocrine and endocrine aspects of the ovary
exocrine: female gametes (oocytes)
endocrine: estrogen, progesterone, androgens
what is the blood supply to the ovary
ovarian artery
what is the epithelium on the outer covering of the ovary
simple squamous (mesovarium-tunica serosa)
what tunic is the capsule of the ovary
tunica albuginea
what are the two main parts of the ovary
cortex and medulla
what is located within the cortex of the ovary
ovarian follicles
corpora lutea
ovarian interstitial cells
stromal elements
what is located in the medulla of the ovary
vessels, lymphatics, nerves

loose CT w/ elastic and reticular fibers
what is the primary innervation to the medulla of the ovary
vasomotor
define oogenesis
formation and development of ova
where do primordial germ cells develop during early embryogenesis
the yolk sac
after development in the yolk sac, where do primordial germ cells go
they migrate to the gonadal ridges in the embryo, become surrounded by ovarian follicular cells and become primary germ cells
when do oogonia become primary oocytes
before or shortly after birth
what happens to primary oocytes after birth
they are arrested until sexual maturity (in dog and horse, will stay as primary oocyte until fertilization)
when does the primary oocyte mature into a secondary oocyte
just prior to ovulation
what is produced after fertilization
ovum
what is an ovarian follicle
cell aggregate (ovarian follicular cells) containing the developing gamete (primary oocyte) and surrounding thecal cells
what is the order of follicular development in the ovary
1. primordial follicle
2. unilaminar primary follicle
3. mulilaminar primary follicle
4. vesicular or antral (secondary) follicle
5. mature (graafian, tertiary) follicle
what does the primordial follicle look like
it's a primary oocyte surrounded by a single layer of flat ovarian follicular cells
what is the unilaminar primary follicle
primary oocyte surrounded by cuboidal or columnar ovarian follicular cells
what are multilaminar primary follicles
primary oocyte surrounded by multiple layers of ovarian follicular (granulosa) cells

membrane granulosa (stratum granulosum of ovarian follicle)
what develops in the multilaminar primary follicle between the oocyte and ovarian follicular cells
zona pellucida
what do the stromal cells of the multilaminar primary follicle differentiate into and which one is functionally most important
theca folliculi interna (most important): produce androgens

theca folliculi externa
within the vesicular follicle, granulosa cells secrete ____ and form ____
liquor folliculi

follicular antrum
what is the cluster of granulosa cells that surround the oocyte
cumulus oophorus
what forms and nourishes the oocyte
corona radiata
what lines the antrum of the follicle
granulosa cells
the oocyte is surrounded by a thick glycoprotein layer, the ___ and an outer cellular layer, the ___
zona pellucida

corona radiata
what follicle protrudes from the surface of the ovary
mature follicle (preovulatory follicle, graafian follicle)
what is follicular atresia
degeneration that may occur at any point in the developmental sequence
what is ovulation
the rupture of a follicle and the release of an oocyte
what is the site of rupture on the ovulated follicle called
follicular stigma
what is the released oocyte surrounded by
zona pellucida and corona radiata
what species loses its corona radiata at ovulation
cows
what happens to the site of the ovary after ovulation
the follicular wall collapses and a corpus hemorrhagicum forms
within the corpus luteum what happens to the granulosa cells that formerly surrounded the oocyte
they transform into granulosa lutein cells
what causes the yellow pigment seen in most species in the corpus luteum
lutein
