Q

What is the function of epididymis?

16
Q

What is the function of seminal vesicles

A

add fructose and prostaglandin (alkaline) to support sperm

17
Q

What does the central zone surround?

A

the ejaculatory ducts

18
Q

What does the transitional zone surround?

A

prostatic urethra

19
Q

Which zone is immediately adjacent to the urethra

A

periurethral zone

20
Q

T/F Prostatic epithelium is cuboidal

A

False, it is heterogenous, a mixture off different cell types

21
Q

What is the function of prostatic secretion

A

clot the ejaculate, and then free the sperm to move
