Male Repro Flashcards
What are the main structures of the male repro?
-testicle
-epididymis
-ductus deferens
-penis
Why is it important that the testicular vein forms the pampiniform plexus?
having a large amount of venous surface area surrounding the artery helps to cool down incoming blood to an appropriate temp. for the testicle
What is the role of the proper lig. of the testicle?
connect testicle to tail of epididymis
What is the role of the lig. of the tail of the epidiymus?
remnant of gubernaculum that anchors testicle to scrotum
What is the parietal vaginal tunic?
the vaginal tunic tissue facing the body wall
What is the visceral vaginal tunic?
the vaginal tunic tissue facing the ductus deferens, testicular a., and testicular v.
What is the meso-ductus deferens?
the double layer of vaginal tunic tissue forming the sheath around the ductus deferens
What is the mesorchium?
the double layer of vaginal tunic tissue forming the sheath around the testicular a. and v.
What is the role of the gubernaculum?
-shrinks and pulls testicles into scrotum
-gets testicles outside of body and to the right temp. for sperm production
What is the role of the cremaster muscle?
contract when testicle is too cold and pull it towards the warmer main body mass
What are the characteristics of the tunica dartos?
-muscle in scrotum
-allows scrotum to shrink and hold testicles to body when cold
What is a closed castration?
-spermatic cord not open to outside
-two sutures to close off entire cavity within spermatic cord
What is an open castration?
-spermatic cord open to outside
-individual sutures to tie off ductus deferens and testicular a. and v.
What are the pros and cons of a closed castration?
pro: peritoneal cav. is not opened and is not exposed to infection
con: do not get a good tie off on each structure; potential for slippage
What are the pros and cons of an open castration?
pro: tight tie off on each structure
con: open peritoneal cav. exposed to potential infection
