Female Histology Flashcards
name the four follicles in the growth process in ovaries
primordial
primary
secondary
graafian (tertiary)`
what is the appearance of a primordial follicle?
primary oocyte with single layer of follicular cells
what type of egg in primordial follicle?
primary oocyte
how are follicular cells that surround a primordial follicle connected?
by desmosomes
what stage of meiosis is a primordial follicle arrested in?
prophase of meiosis 1
what is around the primary oocyte in a primary follicle?
zona pellucida
what is the zona pellucida?
amorphous layer surrounding primary oocyte in primary folicle
what are the two types of primary follicles?
unilaminar and multilaminar
what is the diff in unilaminar and multilaminar primary follicles?
unilaminar only has one folliculr cell layer and multilaminar has many layers
outside of the follicular cells in a multilaminar primary follicle is what?
theca cells…theca interna and extern
what is in the theca interna?
inner cellular layer
what is in the theca externa?
firbouslayer
which follicle becomes dependent on FSH for growth?
secondary follicle
what is the defining characteristic of a secondary follicle?
when fluid fills the spaces between the granulosa cells
in a secondary follicle, what is the fluid that is in between the granulosa cells?
liquor folliculi
what do the fluid filled spaces eventually do?
coalesce to make an antrum
which follicle ovulates?
graafian
is graafian follicle dependent on FSH?
no
what does the graffian follicle make to shut off FSH?
inhibin
where is the primary oocyte in a graafian follicle?
off center on a small mound of granulosa cells
what are the granulosa cells called that surround the zona pellucida in the graafian follicle?
corona radiata
does the graafian follicle complete meiosis 1?
yes
where is graafian follicle stopped in meiosis 2?
at metaphase
what triggers the completion of meiosis 1?
LH surge
what does the graafian follicle form after ovulation?
corpus luteum
what are the two cells of the corpus lteum?
granulosa lutein cells
theca lutein cells
what are atretic follicles?
degenerating follicles after graafian follicle is ovulated
what are the three layers of the fallopian tubes?
mucose muscularis serosa
what is special type of cells int eh mucosa layer of the tubes?
peg cells and ciliated cells
what is the serosa made of in the tubes?
simple squamous epitheliem
what is the role of the peg cells in the tubes?
secrete nutrients to nourish sperm and cytokines
what are the three layers of the uterine wall
endo
myometrium
adevntitia
what is epithelium of the endometrium?
simple columnar
the stroma of the endometrium has a lot of what?
simple tubular glands
what are the two layers of the endometriu,?
functional and basal
what is the role of the functional layer of the endometrium?
thick superficial layer that ets sloughed off and is mainly responsive to hormonal changes
what is the role of the basal layer of the endometrium?
deep layer tht is preserved during menstruation and has basal cells that remake the functional layer
name the two artery types of the endometrium
coiled and straight
where do coiled arteries go?
into both basal and functional layer
where do straight arteries reside in endometrium?
only in basal layer
what is the epithelium of the cervix?
mucus secreting simple columnar
does the vagina have glands?
no..get mucus from cervix glands
what are the three layers of vagina?
mucosa
muscularis
adevntitia
what is special thing that is present in mucosa of vagina?
glycogen
why is glycogen in mucosa of vagina?
used by bacteria to make lactic acid to lower pH during follicular phase of menstural cycle to inhibit pathogens
