reproductive Flashcards
BOTH ORGAN HAVE ACCESSORY REPRODUCTIVE ORGANS
true
Gonads produce
gametes via meosis
fuse to form
zygote
mitosis occurs because
new cells are needed for tissue growth or repair
what produced sperm
semiferous tubules
inside the the lobules of the tested
semiferous tubules
two cell type
spermstogenic
and sustentacular support sperm production
interstitial cell
produce testosterone
activated by LH
testes two function
sperm production and secrete testorone
push cell and fluid from semiferous tubules to epididymis
myoid cell
ductus deference layer
mucosa
PSCEE
SMC
MUSCULARIS
receives sperm from ductus deferens at the seminal vesicle
ejaculatory duct
urethra
transport both urine & sperm
penis structure
root - attach to body wall
body - contain erectile tissue
glan penis - external urethral orifce produce located (outside
epididymis
storage and maturation
loose skin call of penis
circular fold prepuce
internal penis layers
erectile bodies -spongy network of connective and smc
- corpora convernosa- paired erectile bodies (2 of them
corpus spongiosum - at base
ductus deference store
only sperm that’s hadn’t been ejact yet
seminal fluid
fructose sugar that sperm utilize for ATP
prostaglandins- stimulate smc contract
coagulating protein
PH OF SEMINAL IS ALKALINE TO NEUTRALIZE ACID
prostate fluid explained
tubular gland & smc
citrate - sugar that sperm can utilize
PSA- break down the clot from female reproductive tract letting sperm move freely
Antimicrobial chemicals - stop the female’s reproductive system from getting infected
cremaster muscle
control height of the testes
which also control temperature of it based on movement
sustentaculae cells
produce inhibin
give nutrients
has phagocytize which recognizes damage cell from sperm & break it down
spermatids
only cell that can move on their own in the human body
Head - contain nucleus and acrosome
mid piece - contain mitochondria
tail- flagellum help move
acrosome has
tip of the head that’s enzyme to fertilize
egg
how long it take sperm cell to reach epididymis
12 days & a month for viable
entire process take 60-70 days
inhibitin & testerone do what to fsh & gnrh
what feedback is that
decrease inhibin release in fsh
testosterone reduce gnrh secretion negative feedback
accessory glands and what they do
seminal vesicles
prostate gland
erection
psn release nitric oxide from blood vessel
ejaculation & stages
sns
emission- movement semen into urethra
expulsion-semen pushes out from urethra
ovaries region
ovarian cortex - superficial region - production of gametes begin in saclike , develop
ovarian medulla- inner region blood vessels lymphatic vessels and nerve found
ovaries function
produce estrogen & egg
uterine tube layers
ishmus proximal end connect uterus
ampula distal end connect of uterine tube
infundinulum - funnel shape move stuff
fertilization happens in uterine tube
true
uterus region
fundus - roud region , entrance of uterine tube
body- main region middle
cervix - neck
uterus layer
perimetrum outermost layer
myometruim - middle layer smc
endometrium inner most layer line with uterine cavity / simple columnar epi
vagina
rugae
lactic acid -maintain PH
EPITHELIA CELL SECRETE GLYGOGEN
vulva
external reproductive structures
mammary gland is what feedback
positive feedback
milk pasthway
alveoli > lactiferous duct > lactifetous sinus > nipple
what pushes it is myoepithelia cell
small protrusion composed of erectile tissue
clitoris
vesicular follicles
large cavity called antrum ( complete meiosis 1 to form secondary oocyte and first polar body
corpus lutem and albicans
leftover follicles produce estrogen progesterone
and scar tissue left after corpus lutem dies -albicans
surround nipples
areola
the endometrium contain of two layers
stratum functionalist - detach from the uterine wall. shed usually monthly during menstruation
stratum basalis- does not shed . replace stratum functionalist at end of menstruation build it
corpus lutem produce
estrogen progesterone
menarche
first episode of menstrual bleeding
menopause
point where menstruation has not occurred for more than one year
placenta function and where it’s at
uterine wall between fetus & umbilical cord
shed after birth
Exchange oxygen nutrient waste between mother and fetus
Produce hormones to support pregnancy (Hcg)
Blood separated by Plancetal and barrier
what makes a extraembryonic & function
amnion- enclosed embryo with fluid
penetrated ( let it pass through )only by umbilical cord shed after
protect embryo from trauma
chroriom- outermost layer
protect embryo
Gas exchange storage and
removal waste nutrition uptake
