male,
what is the goal of males?
th make viable sperm
what are the 6 components of the male repro system?
spermatic cord
scrotum
testis
excurrent duct system
accessory sex glands
penis
describe the five steps of sperm production:
- high speed manufacturing and air conditioning
2.finishing shop for fluid absorption, membrane changes, stabilization, motility and cytoplasmic droplet translocation - shipping and storage for housing sperm for ejaculation
- alterations and packaging- metabolic substrates, surface coatings, transport for spermatozoa
- delivery system- erection, protrusion, emission, and ejaculation
define erection
penis grows firmer, larger, and engorged, which is triggered by the parasympathetic nervous system
define protrusion
penis protrudes out of the sheath
define emission
discharge from accessory glands, sperm moves to urethra
define ejaculation
expulsion of semen from pelvic and penile urethra
what is the pathway of sperm?
testis (2)-epididymis (2)-ductus deferens (2)-urethra-accessory glands-penis
what are the vas deferens
a tube that deposits into urethra
what makes up the spermatic cord
pampiniform plexus, vas deferens, cremaster muscle, and testicular artery
why is testicular thermoregulation needed
because spermatozoa need to stay 4-6ºC cooler
what aids with thermoregulation
pampiniform plexus, scrotal skin, cremaster muscle, and tunica dortos
what does the pampiniform plexus do
countercurrent exchange; helps with warming and cooling blood
what does the scrotum do
a temp sensor and protective sac
what does the tunica dartos do
plays a large role in temp control and requires testosterone to work
