Pelvis Part 3 (penis) Flashcards
testes
-originate inside the abdominal cavity
-guided by gubernaculum
-drawn superior when cold via cremaster muscle
epididymis
-where sperm mature
-head body and tail regions
ductus deferens
-sperm ejected from epididymis into ductus deferens during ejaculation
-ascend superiorly to enter pelvic cavity vis inguinal canal and arch over ureter and expand to join duct of the seminal vesicle to form ejaculatory duct
seminal glands
produce alkaline secretion that contributes to formation of semen
prostate
-surrounded by prostatic capsule and prostatic sheath
-prostatic ducts
-has different lobes separated by urethra and ejaculatory ducts
prostatic ducts
open into the prostatic urethra through 10-12 openings that secrete proteolytic enzymes into the semen
testes supplied by
testicular arteries
ductus deferens supplied by
deferential arteries of superior vesical arteries
seminal glands and ejaculatory duct supplied by
inferior vesical arteries
prostate supplied by
prostatic arteries of the internal vesical arteries
all penis parts drained by
veins accompanying the arteries with corresponding names
ductus deferens, seminal glands, ejaculatory ducts, and prostate innervated by
sympathetic nerve fibers
