Male Reproductive System

Fx: sac that holds and regulates the temperature of the testes

tunica albuginea

Fx: divides the testes into lobules with 1-4 seminiferous tubule per lobule

tunica vaginalis

Fx: serous membrane that covers the testis and protects testis from friction

cremaster muscle

Fx: elevates or suspends testes to control temp

scrotal septum

Fx: divides the scrotum into two sacs

penis

Fx: male sex organ, transport and deliver sperm during intercourse

corpora cavernosa

Fx: fill with blood to create erection

corpus spongiosum

Fx: prevent conpression of urethra during erection

glans penis

Fx: protection of corpora cavernosa during intercourse

prepuce (foreskin)

prostate gland

Fx: adds a chemical fluid to the semen

seminal vesicles

Fx: secrete fluid rich in sugar that nourishes and helps sperm move

Fx: semen transportation

membranous urethra

Fx: semen transportation

spongy urethra

Fx: semen transportation

spermatic cord

Fx: encloses nerve fibers, blood vessels, and lymphatics that supply testes

testicular artery

Fx: provides blood supply to the testes

pampiniform plexus

Fx: veins that drain the testes and absorb body heat from the testes and scrotum
