what is the function of
crus
blood enters and flows through penis
ductus deferens
carries sperm from epididymis to urethra
penile urethra
carries urine and sperm
Visceral Vaginal Tunic
closest to testes,covers tunica albuginea and testes
Ischiocavernosus
contractions regulate erection
Bulbospongiosus
empties male urethra, forms ventral surface below urethra
pampiniform plexus
helps cool the blood entering the testes
ductus deferens
transports sperm from the epididymis to the urethra
bulbourethral glands

seminiferous tubules
site of sperm production
Epidydimis
--sperm are stored here to mature
urethralis
-It can act as a voluntary sphincter to the urinary bladder -Contracts during ejaculation to move semen through the pelvic urethra
tunica albuginea
Dense connective tissue surrounds testes
cremaster muscle
Muscle that pulls the scrotum closer to the body in cold temperatures and relaxes to let the testicles be farther away from the body in warmer weather
Rete Testes
Produce gametes, sperm and hormones
Mediastinum
Thick connective tissue, keeps retes testes open
scrotal fascia
Thin sheet of fibrous tissues
Parietal vaginal tunic
inner most layer of tunic
prostate
known for g spot and is along the urethra
Fibroelastic
lots of dense connective tissue, sigmoid flexure; bull, boar, ram
retractor penis
maintains sigmoid flexure
skin of scrotum
many sweat glands, regulates degree of sweating and respiratory
Musculovascular
more vascular and muscular. human, dog, tom, stallion.
Tunica Dartos
muscle that lines scrotum, regulation of temp
vesicular glands
