– Clear urethral tract
– Vehicle for sperm transport
– Plugging female reproductive tract (rodents)
These are fuctions of the __________

A

Accessory Sex Glands

20
Q

What Accessory Sex Glands are Paired?

A
  • Ampulla
  • Seminal Vesicles (vesicular glands)
  • Bulbourethral glands
21
Q

The ______________ is not paired, and is divided into two major portions:
- Large, distinct portion referred to as the body
- A more disseminate portion that can’t be palpated as easily or located easily

A

Prostate

22
Q

What species only has a prostate gland?

A

Canine

23
Q

What species has a bulbourethral gland and prostate gland?

A

Cats

24
Q

What species have all four accessory sex glands?

A

Horses and Ruminant

25
Q

What species has Seminal vesicles, Bulbourethral glands and prostate?

A

Swine

26
Q

What species achieves erection through dilation or engorgement of vascular spaces?

A

Stallion

26
Q

What species achieves erection through dilation or engorgement of vascular spaces?

A

Stallion, Canine

27
Q

In what species is the testes more upright, and tail of the epididymis is towards the ventral aspect of the animal?

A

Bull

28
Q

In what species is the testes horizontal in location?

A

Horses, Dog

29
Q

In what species is the testes upside down compared to a lot of the other species?

A

Boar

30
Q

What species have a Fibroelastic Penis?
(Thick capsule/ Tunica albuginea)

A

Boar, ruminants

31
Q

Why does very little erection take place in a fibroelastic penis?

A

Because it is a very thick capsule around the penis and a thick fibrous connective tissue (tunica albuginea)
- this is why the sigmoid flexure is a requirement for these species

32
Q

What species has a vascular penis or a vasomuscular penis (Thin Capsule) ?

A

Horses, Carnivores

40
Q
