– Prostate
– Testis
• (ii) What is B?
– Penis
– Pelvic Urethra

D
Canine – Contrast injection - arteries
• (iv) What is D?
– Os Penis
– Pelvic Urethra
– Penile Urethra
 Correct 
• Yes! A is the Urinary
Bladder!
Canine
• It appears very white or radioopaque on this image because
radiographic contrast medium
has been introduced into it.
• It is also not completely full
which is why the walls appear
irregular.
• Try (ii)!
• Choose a new question.
Urinary Bladder
 Incorrect 
• No, A is not the Prostate.
• The Prostate is not usually
visible on x-rays.
• The Prostate surrounds the
urethra as it exits the
bladder - its location is

outside the body expect
when they have been
retained in a condition
called Cryptorchidism.
• Try again!

Feline
Testes
 Correct 
• Yes! B is the Pelvic Urethra!
• The Urethra is not usually visible
on x-rays.
• It appears very white or radioopaque on this image because

urethra
• Try (iii)!
• Choose a new question.

Testes
• They are outside the
body as gamete
production is optimal
below body temperature.
• Try (iv)!

Bladder is located
within the abdomen!
Urinary Bladder
• Try again!
• Choose a new question.
 Incorrect 
• No, C is not the Prostate.

surrounds the urethra as it exits
the bladder - its location is
shown by the circle.
• Try again!
• Choose a new question.
 Correct 
• Yes! D is the Os Penis!
• This structure is bone
opacity and is therefore
visible on x-rays.
– Remember, only cats and dogs
have an Os Penis!
• Try Male Reproduction Q2!
• Choose a new question.
Os Penis
 Incorrect 
• No, D is not the Pelvic Urethra.
• Remember: The Pelvic Urethra
is located within the pelvis
and becomes the Penile
Urethra once it enters the
penis.
• The urethra is not visible on xrays unless contrast medium
has been introduced into it
• Try again!
• Choose a new question.
Pelvic Urethra
Penile Urethra
Root of the Penis
 Incorrect 
• No, D is not the Penile
Urethra.
• The Penile Urethra does run
through this region but is not
visible on x-rays unless
contrast medium has been
introduced into it.
