- epididymis
- ductus deferens
- seminal gland
- ejaculatory ducts
- prostate gland
- bulbourethral gland
2
Q
Structures in male genitalia that provide transport and activation of sperm
A
-testis
- epididymis
3
Q
Structures in male genitalia that contribute to semen production
A
- testes, seminal gland, prostate gland and bulbourethral gland
4
Q
structures associated with the male urethra
A
- seminal gland
- prostate gland
- bulbourethral gland
- internal urethral sphincter
- external urethral sphincter
- urethra (duh)
5
Q
portions of the male urethra
A
- pre-prostatic
- prostatic
- membranous
- spongy
6
Q
role of seminal gland in semen production
A
- creates thick alkaline fluid with fructose (energy) for sperm
- create coagulating agent
7
Q
role of prostate gland in semen production
A
- create a thin opaque fluid to activate sperm
8
Q
role of bulbourethral gland in semen production
A
- lubricates spongy urethra
- neutralizes acidity of urine left in the urethra
9
Q
Structures that make up the ejaculatory ducts
A
union of the ducts of seminal glands with the vas deferens
10
Q
features of the prostatic urethra
A
- urinary and reproductive tracts merge here
- includes the urethral crest, seminal colliculus, prostatic sinuses, prostatic ducts, ejaculatory ducts
11
Q
locations of structures in prostatic urethra
A
- urethral crest –> longitudinal ridge on posterior of urethra
- prostatic sinus –> each side of the crest
- seminal colliculus –> enlargement of crest, gives openings to ejaculatory ducts
- openings of prostatic ducts within the prostatic sinus
12
Q
openings on seminal colliculus
A
- 1 utricle opening
- 2 ejaculatory duct openings
