Section 1

Question Answer
primary sex organs are called whatGonads
What are Gonadstestes and ovaries
what are gametes sex cells
What are accessory reproductive organsDucts, glands, external genitalia
role of sex hormonesdevelopment, function, maintain reproductive organs, sex behavior/drives, growth and development of many other organs/tissues
testes functionproduce sperms that move through system of ducts
testes contain what seminiferous tubules which is the site of sperm production
spermatogenesissequence of events produces sperm in seminiferous tubules of testes
memorize

Section 2

Question Answer
sperm region head contains DNA and enzymes as a "helmet" to penetrate and enter egg
sperm region midpiececontains mitochondria
sperm region tailtypical flagellum produced by centriole
spermatic cells do whatgive rise to sperm
mitosis of spermatogonion begins whenpuberty
What happens to spermatidslose excess cytoplasm and elongate into sperms
spermatogenesis spermatids become sperm
where is the location of epididmysisOn top of testes/scrotum
memorize

Section 3

Question Answer
epididmysis functionsite of sperm maturation (40-60 days), non motile sperm becomes motile and nourishes stored sperms
vas deferens locationTube extending from epididmysis
vas deferens functionconvey sperm from epididmysis toward urethra and storage/reabsorption of sperm
ejaculatory ducteject sperm/seminal vesicle secretions from urethra to exterior
seminal vesiclesaccessory gland, produce seminal fluid that contains fructose, prostaglandinds to help widen external part of cervix and 70% volume of semen
prostateaccessory gland that secrete milky slightly acidic fluid, contain citrate, nutrient for sperm health, enzyme to help liquify semen and plays a role in activation of sperm
cowpers glandhelps lubricates glans penis and neutralize acidic urine
semen compositionmix of sperm and accessory gland secretions
memorize

Section 4

Question Answer
Semen contains whatNutrients (fructose), process and activates sperm/facilitate movement and alkalinity neutralizes acid in male urethra/female vagina
hormonal regulation of male reproductive system contains whatGnRH in the hypothalamus, FSH and LH In pituitary
GnRH function in male reproductive systemstimulate anterior pituitary to secrete FSH/LH
FSH function in male reproductive systemcauses spermatogenic cells to be receptive to testosterone
LH function in male reproductive systemstimulates Interstitial cells to release testosterone
Secondary characteristics for male off testosterone activityappearance of pubic, axillary and facial hair, deepen voice, growth of chest, skin thickness/become oily and bones grow and increase in density
what chromosome is needed for one to be male chromosome wiseY chromosome
memorize

Secton 5

Question Answer
ovaries are whatprimary female reproductive organ, secrete estrogen and progesterone
accessory ducts for femaleuterine tubes, tubes and vagina
internal genitaliaovaries and internal ducts
Ovaries are located wherepaired organs on each side of uterus
Ovarian cyclemonthly cycle of events associated w the maturation of an egg
follicular phaseday 1-14, grows graffian follicle, produces estrogens, antrum formed, surge of LH causes end of this phase
ovulation phaseday 14, surge of LH causes ovary wall rupture and expels secondary oocyte
luteal phaseruptured follicle collapses and forms corpus luteum
what does the corpus luteum dosecrete progesterone, and some estrogen
memorize

Section 6

Question Answer
GnRH in females does whatstimulate release of FSH and LH (Day 1)
FSH does what in females in the cyclestimulates maturation of primary follicles into graffian follicles
What does estrogen do in the cycleestrogen is released from graffian follicles which causes a sudden surge of LH
LH does what in the cyclestimulates completion of follicular phase and triggers ovulation (day 14)
Fallopian tubes do whatreceive ovulated oocyte and provide a site for fertilization
Uterine (menstrual) cycleinvolves changes in uterus each month in response to ovarian hormones in blood
endometriummucous membrane lining the uterus that thickens during menstrual cycle in prep for possible implantation of embryo
menstrual phaseDay 1-5 uterus sheds all but deepest parts of endometrium (bleeding)
Proliferative phaseday 6-14 Time after menstruation and before next ovulation, when lining of uterus grows and thickens
secretory (post ovulatory) Phaseday 15-28 time after ovulation - endometrium preps for implantation of embryo
memorize

section 7

Question Answer
Function of estrogenpromote oogenesis and follicle growth in ovary, growth of breasts, growth of axillary and pubic hair
memorize
