-the visceral tunica vaginalis and the parietal tunica vaginalis?
Where do the sperm travel to on their way to the pelvic cavity? (Describe the route)
-released into the "pipes" of the testes -epididymis -ductus deferens/vas deferens -ductus deferens passes through the spermatic cord -ductus deferens enters the pelvic cavity through the inguinal canal
-worm-shaped structure sitting on top of and along the length of each testis
-suspends the testes inside two fibromuscular sacs (scrotum)
What are the two fibromuscular sacs that make up the scrotum called?
-dartos muscle -cremaster muscle
What is the role of the dartos muscle and the cremaster muscle?
What is the dartos muscle made from?
Where is the dartos muscle found?
-woven into the scrotum
What is the cremaster muscle made from?
Where is the cremaster muscle found?
-surrounding each testicle
Where does the ductus deferens run once it enters the pelvic cavity?
-enters the pelvic cavity through the inguinal canal -wraps around the roof and posterior of the urinary bladder -enlarges posteriorly (ampulla) -becomes the ejaculatory duct -becomes the urethra -urethra travels inside the penis
