|
male reproductive system
|
transport sperm
make sperm secrete male sex hormone |
|
|
testes
|
suspended in scrotum
make sperm secrete testosterone |
|
|
seminiferous tubules
|
where sperm is formed
(in testes) |
|
|
spermatogenisis
|
formation of sperm through maiosis so that the genetic material is split
|
|
|
structure of sperm
|
head-contains DNA chromosome
Acrosome- contains enzymes that llow sperm to enter egg tail- propels sperm forward midpiece; contains mitochondria (cellular energy) |
|
|
epididymis
|
location where sperm matures, become motile, secretes glycogen
|
|
|
vas deferens
|
propels sperm during ejaculation
|
|
|
seminal vesicle
|
regulate the ph of sperm waste, produces fructose for sperm energy during the long journey up the vagina!!!
|
|
|
prostate gland
|
secretes substance that causes sperm to move
makes the semen solution more BASIC (not acidic) |
|
|
bulbourethral gland
|
bulbous gland next to urethra, coats urethra so sperm aren't damaged (when boys pee)
mucus SPEEDS the way out |
|
|
semen
|
the fluids from seminal vesicle, prostate, bulbourethral gland, and of course the sperm themselves!
|
|
|
scrotum
|
external reproductive organ
sack like structure that holds the testes responds to temp: to hot....scrotum moves away from body, too cold- scrotum cuddles testes in |
|
|
penis
|
external organ
muscular tune that engorges with blood during ejaculation |
|
|
urethra
|
external organ
deposits urine and semen |
|
|
erection
|
tissue in penis fills with blood and prepares for penetration
|
|
|
emission
|
combination of all testicular fluids....special sauce
|
|
|
testosterone actions
|
increased facial hair
thickening of larynx broadening of shoulders skeletal changes (thicker bones smaller pelvis) thicker skin |
|
|
ovaries
|
"ovum factory" female primary sex organ
|
|
|
ovarian follicles
|
(in ovaries) where ovum develops during menstruation follicles rupture
|
|
|
ovum
|
the cell containing reproductive information....become the baby, merges with sperm
|
|
|
zona pellicuda
|
extracellular matrix of ovum
|
|
|
Oogenisis
|
ovum formation
|
|
|
ovulation
|
release of the most mature ovum
|
|
|
uterus
|
location of fertilized embryo implant
myometrium layer-muscle tissue endometrium-inner tissue also parametrium |
|
|
cervix
|
neck of uterus
protects from outside world "barrier" for sperm |
|
|
vagina
|
9cm long tube recieves sperm + penis
|
|
|
labia majora
|
external organ
protects reproductive structure |
|
|
labia minora
|
external organ
protects reproductive structure inside labia majora |
|
|
clitoris
|
2cm long erectile tissue
|
|
|
vestibular glands
|
produce mucus
(easier for penis insertion) |
|
|
female sex characteristics
|
breast development
more adipose tissue under skin broadening of hips, thighs and backside |
|
|
hormonal process of ovum production
|
1. hypothalamus triggers gonadatropins in the anterior pituitary to secrete LH and FSH
2. FSH causes follicle to form, the dominant follicle causes a surge in estrogen, triggering the gonadatropins to slightly decrease 3. the estrogen continues to rise and FSH and LH are also triggered to surge 4. when FSH and LH and estrogen are at their highest point, LH triggers the follicle to rupture 5. newly released ovum is released into fallopian tubes and the period of ovulation ends |
