Female Reproductive System Flashcards
the germinal epithelium is a single layer of _____
cuboidal mesothelial cells
the ___ of the ovary contains the follicles
cortex
the ___ of the ovary contains connective tissue and blood vessels
medulla
meiosis begins in utero and is arrested at:
prophase 1
in puberty, FSH stimulates primordial follicles to do 3 things:
(hint: fsh…cells…hormones..)
- acquire more FSH receptors
- folicular cells become granulosa cells
- folicle starts producing estrogen
the theca interna produces:
androsteinedione
space that develops between the granulosa cells is called ___ where you find ____
an antrum, meiosis inhibitory substance (OMI)
the ____ follicle is the follicle that ovulates
graafian
the layer around the zona pellucida of the oocyte in the mature (graafian) follicle is called the ____
corona radiata
outside the corona radiata is the ____
cumulus oophorus
upon ovulation, the oocyte continues meiosis II and is arrested in ____
metaphase II
follicles that don’t make it through meiosis and die are called:
atretic follicles
when the follicle becomes a corpus luteum, the follicles begin secreting
progesterone
the corpus luteum lasts for ____ unless pregnancy occurs
about 12 days
fimbriae
finger like projections that draw the oocyte into the oviduct
isthmus
narrowing of the ampulla
pars interstitialis
where the isthmus passes into the uterine cavity
estrogen exhibits negative feedback if the levels exceed ___
150 pg/mL for 36 hours
a surge in ____ causes collagenic enzymes to erode the wall of the graafian follicle releasing the oocyte
FSH and LH from the pituitary
birth control pills work by increasing the levels of _____ and ____
estrogen, progesterone
injecting a bolus of ___ can induce pregnancy
LH
___ rescues the corpus luteum, preventing it from breaking down
hCG
the ____ of the cervix usually secrete a viscous material. Once a month, the secretion changes to an ____ secretion
simple columnar epithelium, aqueous
cervical cancer arises from the ____ epithelium
stratified squamous non-keratinized
the vagina is lined by _____
stratified squamous non-keratinized epithelium
the Skene gland is homologous to the ___ in males
prostate
Bartholin’s glands are homologous to ___ in males
Cowper’s glands
in the female, the urethra is lined by:
pseudo stratified columnar epithelium
the labia minora and majora are lined by:
keratinized stratified squamous epithelium
the labia majora differs from the minora by:
relatively more sweat glands, sebaceous glands, and hair follicles
The gonads descend in BOTH sexes and are guided by ____ . The testis passes through the deep body wall into the scrotum via the ___ .
- fibrous gubernaculum
- inguinal canal (extends between deep and superficial inguinal rings)
Testis descends behind a fingerlike extension of parietal peritoneum, the____, which pinches off around the testis, forming a sac in the scrotum called ___.
processus vaginalis
tunica vaginalis testis
after descent, ovary ends up in the ____, an extension of the broad ligament of the uterus
mesovarium
gubernaculum attaches to the uterus and becomes the ____ and ____.
fibrous ovarian ligament
round ligament of the uterus
Processus vaginalis
fingerlike projection of parietal peritoneum
extends thro inguinal canal, pinches off to form tunica vaginalis testis (sac that covers the testis).
The proximal part usually disappears but may persist as a congenital, indirect, inguinal hernial sac.
in the abdomen the testes were between these two layers
parietal peritoneum and transversalis fascia (bottom layer)
