A

ampulla

29
Q

The ampulla of the ductus deferens is absent in what 2 species?

A

cat + pig

30
Q

Function of accessory genital glands

A

produce fluid part of ejaculate

31
Q

The diffuse part of the prostate gland in the wall of the pelvic part of the urethra is called:

A

disseminate part of prostate

32
Q

33
Q

In the human and stallion, the vesicular glands is also called ________. Why?

A

seminal vesicles
big lumen like bladder (unlike compactness in other species)

34
Q

The glands in the walls of the vesicular gland secrete _______ to nourish sperm in the female reproductive tract.

A

fructose

35
Q

The vesicular gland is located lateral to what structure?

A

ampulla of ductus deferens

36
Q

Which species do not have a vesicular gland?

A

carnivores (dogs/cats)

37
Q

Function of bulbourethral gland

A

produce thin, clear mucus to lubricate urethra before ejaculation

38
Q

Where is the bulbourethral gland located?

A

where urethra enters bulb of penis

39
Q

The bulbourethral is covered by (smooth/skeletal) muscle called ________ M.

A

skeletal
bulboglandularis M

40
Q

The bulbourethral gland is absent in the _____, while present in the ____.

A

dog
cat

41
Q

Where does the root of the penis attach?

A

ischial bones (hips)

42
Q

The root of the penis has 2 _____ on either side of what structure?

A

crura
ischiatic tuberosity

43
Q

Each crus of the root of the penis is covered by _______ muscles.

A

ischiocavernosus

44
Q

What is the function of the ischiocavernosus muscles?

A

restrict venous drainage to accumulate blood during erection

45
Q

The bulb of the penis is covered by _______ muscle.

A

bulbospongiosus M

46
Q

Function of bulbospongiosus M

A

propulsive/contractile force to propel spermatozoa out

47
Q

Which nerves innervate the ischiocavernosus + bulbospongiosus Mm?

A

caudal rectal N + pudendal N

48
Q

What is different about the bulbospongiosus M in the stallion?

A

goes all the way down to gland penis to urethra for lots of contractile force

49
Q

the root of the penis continues as _______ in the body of the penis which surrounds the urethra.

A

corpus spongiosum penis

50
Q

Each crus at the root of the penis continues as the ________ in the body of the penis.

A

corpus cavernosum penis

51
Q

Corpus cavernosum penis is covered by ________.

A

tunica albuginea

52
Q

The corpus spongiosum penis from the body continues as _________ in the glans penis.

A

corpus spongiosum glandis

53
Q

(T/F) The corpus cavernosum in the body of the penis continues as the corpus cavernosum glandis in the glans penis.

A

False - ends at the body

54
Q

In ruminants and the pig, the penis is considered _______ while it is considered ________ in the horse.

A

fibroelastic
musculocavernous

55
Q

Explain why the ruminants/pig have a “fibroelastic” penis.

A

penis straightens due to relaxation of retractor penis M and pressure allows sigmoid flexure to straight –> erection

56
Q

Explain why the horse has a “musculocavernous” penis.

A

cavernous spaces fill and increase pressure which leads to erection/elongation

57
Q

Straightening of the _______ in the penis of ruminants and the pig causes erection.

A

sigmoid flexure

58
Q

Term for projection of urethra at the distal end of the penis

A

urethral process

59
Q

Which two species have very prominent urethral processes?

A

sheep + goat

60
Q

The _____ has a very short urethral process, while the ____ and ____ do not have one.

A

dog
cat + pig

61
Q

The urethral sinus empties into the _______.

A

fossa glandis

62
Q

The fossa glandis is also called ________. Why?

A

“bean of the penis”
build-up of hardened epithelial secretions

63
Q

2 parts of the male urethra

A

pelvic part
penile part

64
Q

Term for extension of urethra in ruminants and the pig that can cause issue with placing a urinary catheter.
