Reproductive System
Question | Answer |
---|---|
meiosis-cell division result in | gametes |
when sperm and an egg join together they become | a zygote (a fertilized egg) |
sperm are produced in the | testes |
sperm transports through | epididymus, ductus defereus, ejaculatory duct, and urethra |
testes- paired organs in the sac called | scrutum |
testes develop near the | kidneys |
cryptorchidism | undescended testes |
containes several seminiferous tubules | lobe |
sustentacular cells stimulated by testosterone to produce | inhibin |
(LH) hormone to produce | testosterone |
20 foot long coiled tubes | epididymis |
smooth muscle move sperm into | ductus deferens |
vas deferens | ductus deferens |
connective tissue sheath | spermatic cord |
common place for hernia | inguinal canal |
seminal vesicles | paired organs posterior to bladder |
energy source from sperm | fructose |
alkaline liquid | neutralizes acidity of vagina |
paired ducts that receive contents of seminal vesicles and ductus deferens | ejaculatory duct |
prostate gland | muscular gland inferior to bladder surrounding prostatic urethra |
walnut size | prostate gland |
Cowpers gland | Bulbourethral |
contains urethra | penis |
glans penis | the head |
prepuce | foreskin |
surgical removal of foreskin | circumcision |
3 cavities of cavernous tissue | erectile tissue |
process of producing sperm | spermatogenesis |
seminiferous tubules contain stem cells called | spermatogonia |
spermatogonia undergo ___________ to result in 2 diploid cells-one remains a ____________ | mitosis, stem cell |
FSH | follicle stimulating hormone |
intiates sperm production | FSH |
lueinizing hormone | stimulates testosterone production in the testes |
10-14 years old this begins | puberty |
23 | chromosomes |
flagellum | provides motility |
sperm and secretions from the seminal vesicles, prostate gland, and bulbourethral glands | sperm |
male reproductive system | consists of the testes and a series of ducts and glands |
female reproductive system | paired ovaries, fallopian tubes, uterus, vagina, external genitalia |
follicles | 3 stages, primary, graafian, atretic |
cavities that each contain an oocyte | primary follicles |
surround each oocyte | follicle cells |
mature primary follicle | graafian |
graafian follicles become corpus luteum and secretes | progesterone, estrogen, inhibin and relaxin |
atretic follicles | developing follicles that become useless and deteriorate after ovulation of the graafian follicle |
attaches from medial end of the ovary to uterus | ovarian ligament |
broad ligament | fold of peritoneum that covers the ovaries and attaches to the uterus |
process of egg cell formation | oogenesis |
each follicle contains a | stem cell |
production stimulated by FSH | estrogen |
meiosis results in 3 | polar bodies and one egg |
ova production begins at | puberty |
ova production continues until | menopause |
approximately every 28 days | cyclical |
causes ovulation, release of ovum | luteinizing hormone |
uterine tubes or oviducts | fallopian tubes |
fimbriae | finger-like projections superior to the ovary |
fertilization usually takes place here | fallopian tubes |
secretes mucous and implants on the uterus | zygote |
implantation outside the uterus | ectopic pregnancy |
uterus | pear-shaped muscular organ posterior to the bladder |
contains the placenta during pregnancy | uterus |
fundus | superior part where fallopian tubes enter |
main central part | body |
cervix | neck that opens into the vagina |
outer layer | epimetrium |
middle layer | myometrium |
myometrium | contract during delivery |
endometrium | innermost layer |
adjacent to myometrium | basilar layer |
functional layer | regenerated and lost during each menstrual cycle if pregnancy does not occur |
vagina | muscular tube from cervix to vagina orifice |
posterior to urethra | vagina |
the vagina is anterior to the | rectum and anus |
partially covered by a thin membrane called | hymen |
vulva | external genitalia |
small mass of erectile tissue anterior to urethra | clitoris |
mons pubis | fat pad external to pubic sympysis covered in pubic hair |
lateral folds of skin | labia majora |
labia minora | medial, smaller folds of skin surrounding the opening |
secretes lubrication during intercourse | bartholins glands |
bartholins glands | vestibular |
made of lactiserous glands | mammary glands |
modified sweat glands that produce milk | lactiferous glands |
lactiferous glands | alveolar |
stimulated by sucking | oxytocin |
prepare glands | estrogen and progesterone |
influenced by FSH, LH, estrogen, and progesterone | menstrual cycle |
marked by loss of functional layer | menstrual phase |
follicular phase | growth of ovarian follicles |
ruptured follicle becomes corpus luteum | luteal phase |
decreases uterine contraction to aid in implantation | relaxin |
