Definition
ends when mature sperm forms/regular menstrual cycle
Term
menarche
Definition
1st menstrual period,2- 2.5 years after breast develops between 11-15yrs
Term
menopause
Definition
end of menstrual
Term
estrogen
Definition
responsible for female sex characteristics
Term
male
Definition
hormonal change between 10-16yrs old,wet dreams,testosterone levels becomes constant
Term
Female reprod,
Definition
mons pubis,labia majora,labia minora,fourchette,clitoris,vaginal vetibule,perineum
Term
mons pubis
Definition
pad of fat tissue covered by coarse skin and pubic hair-protect symphysis pubis
Term
labia majora
Definition
2 folds of fatty tissue on each side of vaginal vestibule
Term
labia minora
Definition
2 thin soft folds of tissue,secretions from sebaceous glans,bactericidal,lubricate and protect skin of vulva
Term
fourchette
Definition
folds of tissue below vagina-obstetrical perineum
Term
clitoris
Definition
most sensitive-produces smegma-cheese like secretions of sebcaceous glands
Term
perineum
Definition
muscular area between vagina and anus,stretch for birth -site of episiotomy
Term
urethral meatus
Definition
exit for urine
Term
skenes's ducts
Definition
lubricates urethra and vaginal orifice
Term
vaginal introitus
Definition
divides the external and internal genitalia
Term
Hymen
Definition
thin elastic membrane that closes vagina from vestibule
Term
bartholin glands ducts
Definition
lubricates introitus during sexual arousal-not visible
Term
ovaries
Definition
2 almond shaped walnut sizes held by ovarian and uterine ligaments-produces estrogen and progesterone
Term
estrogen
Definition
develops secondary sex characterestics-endometrial growth
Term
progesterone
Definition
thicken uterine lining -decrease causes menses
Term
ovum
Definition
mature during each reproductive cycle-at female has around 2 million -adulthood number in the thousands,
Term
menopause(climateric)
Definition
ovum no longer responds to harmonal stimulation
Term
Fallopian tubes
Definition
passageway for sperm to meet ovum-site of fertilization
Term
Zygote
Definition
fertilized ovum-in fallopian tubes (safe nourishing environment)
Term
transport of ovum or zygote
Definition
fallopian tubes -transports to corpus of the uterus
Term
uterus
Definition
hollow muscular organ-fertilized ovum implants and develops into an embryo
Term
between the urinary bladder and rectum
Definition
uterus (above the vagina)
Term
fundus
Definition
round soft portion on the top (uterus)
Term
Corpus(body of the uterus)mucosal lining
Definition
lubricates vagina,bacteriostatic agent,aklaline environment to shelter deposited sperm,produces muous plug
Term
cervix
Definition
cervical canal w/ opening near uterine corpus
Term
edometruim
Definition
governed by harmone cyclical changes,sloughs off during menstruation
Term
myometrium
Definition
muscular layer
Term
perimetrium
Definition
(epimetrium)outer covering layer
Term
vagina
Definition
passageway for sperm to enter uterus,drainage of menstrual fluid,passageway for delivery of fetus
Term
rugae
Definition
enables stretching during sexual intercourse,delivery of fetus
Term
bony pelvis
Definition
sacrum and coccys-from birth passeway
Term
pelvic floor
Definition
muscles that stabilizes reproductive organs
Term
levantor ani
Definition
supports urethra,vagina,and rectum-kegel excercises
Term
gynecoid
Definition
best pelvis -wide opening for delivery
Term
android
Definition
wedge shqped narrow anterior -more common in males
Term
False pelvis
Definition
supports enlarging uterus-guides fetus into true pelvis
Term
areola
Definition
protects the nipple when baby is sucking
Term
montgomery tubercules
Definition
sebaceous glands within areola-lubricate and protect breast during lactation-15 to 24 lobes separated by fat and fibrous tissues ( coopers ligaments)
Term
lacteferoius ducts
Definition
alveolar glands pass milk through-opens at nipple
Term
prepare glands for milk delivery
Definition
high level progesterone and estrogen
Term
prolactin
Definition
from anterior pitituary stimulates milk production
Term
oxytocin
Definition
hypothalumus causes secretion -stimulates release of milk
Term
ovulation
Definition
14 days before period-corpus luteum turns yellow-secretes progesterone
Term
ova not fertilized
Definition
progesterone and estrogen decrease,endometruim breakdown ,corpus luteum degenerates results in menstration
Term
Fsh/LH
Definition
stimulates maturation of ovarian follicle,ovum and corpus luteum produces increased amount of estrogen and progesterone
Term
ovum is released
Definition
surge of LH
Term
menstrual phase
Definition
1-5 days -endometruim sloughs off,FSH increses, progesterone and estrogen levels low
Term
proliferative phase
Definition
day 6-14-Fsh increasing causing increase estrogen -which thicken endometrium
Term
luteal(secretory) phase
Definition
day15-26 progesterone increasing ,thickening of endometrium
Term
ischemic phase
Definition
day 27-28 progesterone levels decrease causing endometruim to become ishemic
Term
follicle phase
Definition
follicle mature cause of FSH,estrogen increases,signals anterior pituary to secrete LH leads to ovulation
Term
luteal phase
Definition
follicle ruptures-becomes corpus luteum,secretes progesterone-
Term
scrotum
Definition
contains testes,epidiymis and spermatic cord
Term
keeps testes cooler-divided into 2 compartments
Definition
scrotum
Term
testes
Definition
manufacture sperm(spermatozoa)in the seminiferous tubules
Term
epidiymis
Definition
one oe each testicle,carries sperm to penis,stores for 2 to 10 days
Term
vas defens ducts
Definition
mature sperm go here
Term
urethra
Definition
transport both urine from prostate,and semen not at the same time
Term
seminal vesicles
Definition
joins vas deferens to form ejaculatory duct
Term
prostate gland
Definition
provides lubrication
Term
bulbourethral glands(cowpers)
Definition
nourish and protect sperm, from acidic environment within womans vagina
Term
semen
Definition
sperm and seminal plasma
Term
stimulates the production of sperm
Definition
FSH
Term
sertoli cells
Definition
stimulated to nourish sperm
Term
LH(intersitial cell-stimulating harmome)
Definition
causes lydigs cells to produce testosterone
Term
sperm
Definition
2-4ml contains 50 -150 million sperm
can survive for 72 hours in vagina
Term
head nucleus-midpiece mitochondria,tail flagellum
Definition
sperm
Term
testosterone
Definition
proctions of rbc's, increases bmr
