What is the job of the ischiocavernosus
helps maintain erection and compresses venous flow
What does the bulbospongiosus do
What innervates it
lateral aspect of the bulb of the penis and proximal body
-supports pelvic floor
-helps expel all the semen
-pushes blood from the bulb into the body of the penis
pudendal

pulls testes upwards
When do the testes descend
What covers them
3 months before birth through the inguinal cancal
tunica vaginalis
What does the spermatocord contain
testicular blood supply, connective tissue, vas defrens
suspended by the spermatic cord

What temperature is required for spermatogenesis
What adjusts it
2-7 degrees C below body temp

What is the venous vascular attachment for the testes
pampiniform plexus
What does the epididymis do
helps w/ continued sperm maturation
obtain nutrients
obtain testosterone
Where is sperm stored

What does the vas defrens do
helps create seminal fluid
ejaculatory duct
can peristals sperm toward the urethra
