Q

what is the function of the ejaculatory duct?

A

conducts sperm & seminal vesicle secretions to the prostatic urethra

20
Q

what is the function of the male urethra?

A

transports semen from both ejaculatory ducts to the outside of the body

21
Q

list the subregions of the male urethra

A

(1) prostatic
(2) membranous
(3) spongy

22
Q

3 glands secrete fluids to mix with sperm to create what?

A

seminal fluid

23
Q

what is the purpose of seminal fluid?

A

nourishment of the sperm & neutralizes the acidity of the vagina

24
Q

list the three accessory glands associated with the male reproductive system

25
Q

this gland is an elongated hollow organ

A

seminal vesicles

26
Q

where are the seminal vesicles located?

A

on the posterior surface of the urinary bladder, lateral to the ampulla of the ductus deferens

27
Q

what is the function of the seminal vesicles

A

they secrete a viscous, whitish-yellow, alkaline fluid containing fructose & prostaglandins

28
Q

this gland secretes directly into the prostatic urethra

43
Q

what is the function of the bulbourethral gland?

A

secretes mucin for lubrication
