Quiz 6 Flashcards
3 functions of female reproductive system
- produce female gametes 2. Provide environment for fertilization 3. Support fetus until birth
2 cycles of female reproductive system
ovarian and menstrual
what is the ovarian cycle
process during which the oocyte follicle undergoes maturation and the oocyte is ejected from the ovary
menstrual cycle
series of changes in the uterine lining that occur approximately monthly
2 functions of ovaries
produce oocytes and steroid hormones
outer surface of the ovary is covered by what kind of epithelium
simple cuboidal
70% of ovarian cancers arise form where in the ovary?
germinal epithelium
stromal cells of follicle are called
theca
function of follicular theca
provides structural support and some of its cells synthesize estrogen precursors
which layer of theca produces steroid inner or outer
inner
layer of cells that surround the oocyte in in mature follicles
corona radiata
connecting stalk of mature follicle
cumulus oophorus
degenerate follicles
atretic follicles
which layer of theca has smooth muscle
external
ovulation occurs on which day of ovarian cycle
14
ovulation is triggered by
surge of LH
function of corpus luteum
produces progesterone and estrogen
if pregnancy occurs, corpus luteum… if pregnancy does not occur, corpus luteum
persists 4-5 months until the placenta is able to produce necessary steroid hormones degenerates forming corpus albicans
what happens during luteinization
cells increase in size and fill w/ lipid droplets to become steroid secreting cells
in CL former granulosa cells b/c____ former thetca interna b/c _____
granulosa lutein thetca lutein
cells on outside of CL are from theca externa/interna
interna
3 primary follices

3 phases of menstrual cycle
menstrual, proliferative, secretory
3 layers of uterine wall
endometrium myometrium perimetrium
perimetrium is continuous with

coiled
during proliferative phase, how are glands shaped?

steps in spermatogensis
type a spermatoagonia stem cell
type a spermatoagonia progenitor cell
type b spermatoagonia
primary spermatocyte
secondary spermatocyte
spermatid
spermatozoa
spermatogenesis vs spermiogenesis
spermatogenesis—stem cell, meiosis
spermiogensis–spermatid -> mature spermatozoa
LH stimulates which cells
FSH stimulates which cells
leydig to make testosterone
sertoli to make ABP
epithelium of epididymis
pseudostrat w/ stereocilia
t/f seminal vesicles are a deposity for spermatozoa
no
spermatozoa b/c motile in
Epididymis
prostate gland is what classificationof gland
tubuloalveolar
diff b/w breast and prostate histological ID
breast has fat, prostate has smooth muscle
2 types of acquired immunity
humoral
cell mediated
humoral immunity uses which kind of cells
cell mediated uses which kindof cells
b lymp
t lymph
3 APCs
monocyte derived
b lymp
epitheliual reticular cells
immunogen
foreign substance that can elicit an immunite response in a particular host
antigen
a molecule that can react w/ an antibody irrespective of its ability to elicit an immune response
all immune cells have receptors for…
cytokines
IgM affinity?
IgG=where most abundamt, (monomer/dimer), affinity
IgA
1st antibody produced, lower affinity
- Most abundant in blood, monomer, high affinity
- most abundant in body/secretions, dimer, high affinity
which antibody crosses placenta
IgG
which antibody is related to allergic response?
IgE
