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 |
