|
testes
|
|
organ that develop sperm
|
testes
|
|
3 ducts
|
seminiferous tubules
epidydimis vas deferens |
|
tiny tubes inside the testes where sperm development occurs
|
seminiferous tubules
|
|
sperm are matured
caps and gowns |
epidydimis
|
|
tube that transports sperm back inside body
|
vas deferens
|
|
on the distal end of vas deferens...sperm can be stored for up to 4 months
|
ampulla
|
|
directly inferior ot the urinary bladder...gives antibacterial agents to secretions
|
prostate gland
|
|
section ro part of the vas deferens that cuts through the prostate gland that leads to the urethra
|
ejaculatory duct
|
|
bundled together with blood vessels and nerves. The whole thing is surrounded be cremaster muscle which comes down along the base of the testes
|
vas deferens
|
|
3 accessory glands that produce a substance that nurtures the sperm
|
seminal vesicals
prostate bulbourethral gland (cowper's) |
|
emty their secretions into the tube just between the ampulla and the ejaculatory duct
|
sminal vesicals
|
|
large gland just inferior to the urinary bladder gives antibacterial agents to secretions
|
prostate gland
|
|
inferior to the prostate on either side fo the urethra-make special secretions that cleans urethra prior to ejaculation
|
bulbourethral (cowper's)
|
|
divides the scrotum into two separate parts
|
connective tissue septum
|
|
external ridge on scrotum that falls on top of the CT septum
|
Raphe'
|
|
part of the scrotal sac deep to the layer of skin...helps to control temperature of testes
|
dartos muscle
|

|
cremaster muscle and dartos muscle
|
|
major male reproductive gland
|
testes
one of the few glands in the body that is both endocrine and exocrine |
|
Connective tissue within each testes that forms incomplete septa generating compartments called lobules
|
Tunica Albuginea
|
|
forms little compartments inside the testes
|
incomplete septa
|
|
each compartment formed by the incomplete septa
|
labule
|
|
special little cells surrounding the seminiferous tubules and that make testosterone
|
leydig
|
|
process of making sperm...testosterone is required for this
|
spermatogenesis
|
|
the seminiferous tubules are made our of wquarish rather large cells called
|
sertoli cells
|
|
job of the sertoli cells
|
to nurture cells as they turn into sperm
|
|
originating cell that gets stuck to the sertoli cell
|
germ
|
|
type of junctions that are between each sertoli cell
|
tight
|
|
job of the tight junctions between each sertoli cell
|
create blood/testes barrier
|
|
job of the blood/testes barrier
|
to prevent dad's blood from coming in contact with the sperm inside the seminiferous tubule...there are different markers on teh sperm and the blood would want to kill the sperm
