name the function of the scrotum
regulates the temperature of the testes
what are the two muscles that contract in the scrotum and what is their function
cremaster - skeletal muscle bringing testes closer to the body to bring warmth
dartos - smooth muscle wrinkling the scrotum to reduce heat loss
what is the function of the testes
site of sperm production
what are the 3 types of cells found in the testes and what is their function
spermatogenic cells - develop into sperm
sustentacular cells - nourish and support development of sperm
interstitial cells - secrete testosterone
what is the function of the epididymis
matures and stores sperm
what is the function of the ductus deferens
transport sperm from epididymis to ejaculatory duct
(smooth muscle moves sperm by peristalsis)
what is the function of the ejaculatory duct
ejects sperm and seminal vesicle secretions into urethra
(passes through prostate)
what are the three sections of the urethra
prostate urethra
membranous urethra
spongy urethra
what is the function of the urethra
passageway for semen and urine
what is the function of the seminal vesicles
secretes alkaline fluid, fructose, prostaglandins and clotting proteins
how much % of sperm does the seminal vesicles make
60%
what is the function of the prostate gland
secrete citric acid, enzymes and seminalplasmin
how much % of sperm does the prostate gland make
25%
what is the function of the bulbourethral glands
secretes alkaline fluid and mucous
