reproductive Flashcards
internal male reproductive anatomy
epididymis, vas deferens, urethra
accessory: prostate, seminal glands
external male reproductive anatomy
scrotum, testes and penis
what are the two layers or erectile tissue in the penis
corpus spongiosum
corpora cavernosa
prostate gland
surrounds urethra
vas deferens
transports sperm from testes to urethra
when does erection occur
when spaces in erectile tissue fill with blood
where is sperm produced
seminiferous tubules
when is spermatogenesis efficient
at 2 degress celcius below body temperature
spermatagonia
developing sperm cells
sertoli cells
form blood-testes barrier along with tight junctions; regulate sperm development, provide nourishment
leydig cells
produce and secrete testosterone
germ cells
undifferentiated
do not develop into sperm cells until puberty
gives rise to 4 sperm cells
andropause
testicular mass decreases, erectile disfunction, reduced sperm count (even though sperm production continues)
internal female reproductive anatomy
ovaries, ovarian (fallopian tubes), uterus
cervix, vagina
external female reproductive anatomy
vulva
mons pubis, clitoris, labia, urethral and vaginal orifice
mons pubis
pubic region covered by hair
labia (minor/major)
inner and outer folds of skin that cover the vaginal opening
clitoris
pleasure center
primary oocytes give rise to
one ovum
what is produced during monthly cycles
oocytes
ovarium vycle
maturation and release of ovum
uterine cycles
building up and shedding of uterine lining
endometrium
glandular epithelium whose structure varies with phases of the menstrual cycle
builds and sheds
GnRH
controls release of follicle stimulating hormone (FSH) and luteinizing hormone (LH)
Where do FSH and LH act
gonads
LH
promotes release of sex hormones
FSH
promotes gamete production (or maturation)
when does LH spike
during ovulation
fertilization
fusion of sperm and ovum leads to formation of zygote
occurs in uterine tube
dividing blastocyst implants in uterine lining
