Reproductive System Flashcards
purposes of female reproductive system
produces and delivers games and provides nutrition and safe harbor for fetal development gives birth and nourishes infant
where is external genitalia located
perineum
what is in perineum
clitoris, labia minora, labia majora
what are the part of the vulva and pudendum
clitoris, vestibular bulbs and greater and lesser vestibular and paraurethral glands
clitoris
erectile sensory organ (blood supply)
vestibular bulbs
erectile tissue deep to labia majora
greater and lesser vestibular and paraurethral glands
open into vestibular for lubrication
mons pons
fat over pubic symphysis with most of pubic hair
labia majora
thick folds and adipose tissue inferior to the mons has hair
pudendal cleft
fissure between labia majora
labia minora
hairless folds medial of labia majora
labia minora forms
vestibular=urethral and vaginal openings
ova
egg cells
what produces egg cell and sex hormones
ovaries
where do the germ cells develop
outer cortex of ovaries
each egg develops in its
own fluid filled follicle
ovaries are attached to uterus by
ovarian ligament
ovaries are attached to pelvic wall
suspensory ligament
another name for uterine tube
Fallopian tube
ovaries are anchored to broad ligament by
mesovarian
where do ovarian veins lymphatics and nerves travel through
suspensory ligament
fallopian tubes go from
ovary to uterus
infundibulum
flared trumpet shaped distal ovarian end
fimbriae
feathery projections on infundibulum
ampulla
middle and longest part
isthmus
narrower end towards uterus
uterus
muscular chamber pear like shaped that opens to roof of vagina
fundus
broad superior curvature
body (corpus)
middle
cervix
cylindrical inferior end
parts of uterus
fundus, body, cervix
lumen
roughly triangular potential space
what connects lumen to vagina
cervical canal
cervical glands
secrete mucus that prevents spread of microorganisms from vagina to uterus
parts of uterine wall
perimetrium, myometrium, endometrium
perimetrium
external serosa layer
myometrium
smooth muscle middle most of uterine wall
endometrium
inner mucosa, simple columnar epithelial
layers of endometrium
functional layer, basal layer
functional layer
superficial half shed each menstrual period
basal layer
regenerates new functional layer with each menstrual cycle
where is the site of attachment of the embryo and placenta where fetus is nourished
endometrium
endometriosis
growth of endometrial tissue outside of the uterus
vagina glands or no
no
vagina allows for
discharge of mentrual fluid, recept of penis and semen and birth of baby
what forms hymen
mucosal folds
vagina undergoes
metaplasia simple cubiodial then estrogen that transform it into stratified squamous
what does the female reproductive tract develop from
paramesonephric ducts
what do paramesonephric ducts develop into
uterine tubes uterus and vagina
how many eggs is a female born with
2 mil
hormone process of development of reproductive tract
rising levels of GnRH which stimulates A.P. to secrete FSH and LH
first central cycle
menarche
what does menarche require
at least 17% body fat
what stimulates gonadotropin secretion
leptin
anaovulatory
no egg ovulated
where does the production of egg start
fetus
oogonia
stem cell
what uses mitosis to produce 1st oocyte
oogonia
1 oocyte starts meiosis 1 but stops at
prophase 1
when does meiosis continue
puberty
puberty produces a
2ry oocyte and a polar body
2ry is aressted in `
metaphase 2 of meiosis 2 and secreted during ovulation
once 2ry oocyte is fertilized
it will end meiosis 2
mature follicle
follicle with ovum that will ovulate
what holds FSH
mature follicle
preovulatory follicle
Graafian follicle
what stimulated ovarian follicles
FSH
once ovarian follicle are stimulated then
they begin to secrete estrogen proesterone, inhibit and small amount of androgen
what selectively surpasses FSH secretion
inhibin
what triggers ovulation and converts follicles into corpus luteum
LH
what secretes progesterone
corpus luteum
sexual cycle begins with
follicular phase
when does mentruation occur
first 3-5 days of cycle
follicular phase
uterus replaces lost tissue by mitosis and follicles grow by FSH, estrogen secretion
ovulation Is around day
14
ovulation Is stimulated by
increase in LH
once ovum is secreted follicle becomes
corpus luteum
in luteal phase corpus luteum will secrete
progesterone
in luteal phase, as corpus luteum deteriorates
hormone level drops
in luteal phase what breaks down in the last two days
endometrium
climacteric
midlife change in hormone secretion , menopause
when ovaries stop producing estrogen
dry vag mood swings hot flashes increased cholesterol and decreased HDL
what causes hot flashes
vasodilation
during pregnancy, what stimulates the development of milk producing ducts
estrogen
after delivery prolactin does what
stimulates the production of milk
after delivery what does oxytocin do
stimulates the ejection of the milk
shat enlarges at puberty
lips and collagenous tissue over pectorals major
mammary gland
develops within great during pregnancy
breast parts
body auxiliary tail
body
conical to pendulous with nipple as its apex
axillary tail
extension toward armpit
what surrounds the nipple
areola
what attachés the breast to dermis
suspensory ligaments
in breast cancer tumors begins with cells from
mammary ducts
scrotum
ouch of skin, muscle, contains testes
what divides scrotum into right and left
internal median septum
what is perineal raphe
medial seam on scrotum
spermatic cord
connective fissure bundles containing ductus deferent, blood and lymphatic vessels , and testicular nerve
what three ways does scrotum regulate temp
cremaster muscle, dartos muscle, pampiniform plexus
cremaster muscle
strips internal abdominal oblique muscle
dartos muscle
contracts when cold wrinkling the scrotum holding tests against warm body
what mechanism to regulate temperature surrounds testicular artery and spermatic cord
pampiniform plexus
where is the sperm produced
seminiferous tubules
what protects germ cells and promotes this development
sustentacular cells
what produces testosterone
interstitial cells
sutentocytes offer what
support
blood-testis barrier
separates sperm from immune system
what collects sperm from seminiferous tubules
rete testis
inguinal canal
hernia, direct indirect ducts
epididymus
sperm storage for 60 days
ejaculatory duct
through prostate merge through urethra
seminal vesicles
empties into ejaculatory duct
prostate gland
located below the bladder and ejaculatory duct , thin milky secretion forms 30% of semen
benign prostatic hyperplasia
noncancerous enlargement of prostate
half of penis is
internal root
foreskin
prepuce
erectile fissure
single corpus spongiosum two corpora cavernous
testes secrete testosterone in
first trimester of fetal development
what awakens reproductive system
pituitary gonadotropins
puberty in boys
first ejaculation of viability;e sperm in boys
what binds to leydig cells to produce and secrete testosterone and estrogen
LH
if there is a decrease in testosterone then
atrophy of organs, decrease semen and impairs erection and ejaculation
what stimulate spermatogenesis and keeps testosterone levels
FSH
spermatogenesis is regulated in
Sertoli cells
primary stem cell divides by BLANK to produce BLANK
mitosis, 1ry spermatocyte
1ry spermatocyte divide through BLANK to produce BLANK
MEIOSIS 1, 2 haploid cells (2ry spermatocyte)
2ry spermatocyte divide through BLANK to produce BLANK
meiosis 2, 4 haploide cells, spermatids
spermatids mature into
spermatozoa
semen
fluid expelled during orgasm
what 2 things are required for sperm motility
elevated Ph and energy source
sympathetics help reduce
erection
parasympathetic induce
secretion
emission
sns stimulates peristalsis which propels sperm though ducts as glandular secretions are added
