module 2-Female Reproductive anatomy Flashcards
functions of the ovary
cytogenic(produce gametes)
endocrine(secrete hormones)
main hormones released by ovary
estrogen
progesterone
configuration(layers) of ovary
tunica albuginia
cortex
medulla
hilus
tunica albuginia(ovary)
outer covering of ovary made of epithelial cells
cortex(ovary)
houses growth of ovarian structures(corpus luteum, follicles)
medulla(ovary)
loose connective tissue, houses vasculature, major nerves, lymphatic system
hilus(ovary)
supports ovary
influx of blood vessels and lymph
primordial follicle
single layer of squamous cells around the oocyte
primary follicle
a single layer of cuboidal cells, oocyte has grown
secondary follicle
two or more layers of cuboidal granulosa cells
tertiary follicle
early antrum formation and theca layer
dominant/graafian follicle
continued antrum formation and oocyte growht
cumulus granulosa cells
close to oocyte
travel with oocyte post ovulation
mural granulosa cells
further from oocyte
communicate with theca cells
corpus hemorrhagicum
blood clot from newly ruptured follicle
lasts 1-2 days
corpus luteum
required for maintenance of pregnancy
produces progesterone
control ovarian cycle
corpus albicans
scar tissue that remains after CL regresses
eventually morphs into ovarian tissue
why are cows CL yellow, and pigs pink
Diet: cows eat a high-forage diet, forage contains beta keratein which turns it yellow
components of female tube system(7)
oviduct
uterine horns
uterine body
cervix
vagina
vestibule
vulva
layers of female tube system
serosa
muscularis
submucosa
mucosa
serosa
single layer of epithelial cells
muscularis
smooth muscle layer
submucosa
houses blood vessels, lymph nerves
mucosa
secretory layer(hormones and mucus)
broad ligament
supports reproductive tract
mesovarium
Broad ligament that supports ovary
mesosalpinx
broad ligament that supports oviduct
mesometrium
broad ligament that supports uterus
uterine structures
body
horns
uterus functions
development of offspring(pre/post implantation)
sperm survival
regulation of cycle
parturition
layers of the uterus
perimetrium
-outer layer(serosa)
myometrium
-muscle layer(muscularis)
endometrium
-secretory lining(submucosa and mucosa)
bicornuate uteri
highly developed uterine horns(litter bearing animals)
bicornuate uteri
poorly developed uterine horns(single offspring)
duplex uteri
two cervixes
simplex uteri
no uterine horns(primates, humans)
cervix structure
secretory and ciliated cells lining cervix
functions of cervix
physical barrier to protect the uterus
chemical barrier
sperm function and storage
