  3. Male Male Reproduction Q1 Male Reproduction Q2 Female Female Reproduction Q3 Female Reproduction Q4 Reproduction Imaging

  4. Male Reproduction Q1 B • (i) What is A? • Urinary Bladder • Prostate • Testis • (ii) What is B? • Penis • Pelvic Urethra • Spermatic Cord • (iii) What is C? • Urinary Bladder • Prostate • Testis • (iv) What is D? • Os Penis • Pelvic Urethra • Penile Urethra A Canine – Contrast Injection C D Canine – Contrast injection - arteries

  5.  Correct  • Yes! A is the Urinary Bladder! • It appears very white or radio-opaque 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. Canine Urinary Bladder

  6.  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 shown by the circle. • Try again! • Choose a new question.

  7.  Incorrect  Feline • No, A is not the Testis. • The Testes are found outside the body expect when they have been retained in a condition called Cryptorchidism. • Try again! • Choose a new question. Testes

  8.  Correct  • Yes! B is the Pelvic Urethra! • The Urethra is not usually visible on x-rays. • It appears very white or radio-opaque on this image because radiographic contrast medium has been introduced into it. • It is continuous with the penile urethra • Try (iii)! • Choose a new question. Penile urethra

  9.  Incorrect  • No, B is not the Penis. • The Root of the Penis is marked on this x-ray. • Try again! • Choose another question. Root of the Penis

  10.  Incorrect  • No, B is not the Spermatic Cord. • The Spermatic Cord is not visible on x-rays as it is a soft tissue structure and is too small to be seen. • Try again! • Choose another question.

  11.  Correct  • Yes! C is the Testis! • They are outside the body as gamete production is optimal below body temperature. • Try (iv)! • Choose a new question. Feline Testes

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

  13.  Incorrect  • No, C is not the Prostate. • Remember: The Prostate is not usually visible on x-rays. It surrounds the urethra as it exits the bladder - its location is shown by the circle. • Try again! • Choose a new question.

  14.  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

  15.  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 x-rays unless contrast medium has been introduced into it • Try again! • Choose a new question. Pelvic Urethra Penile Urethra Root of the Penis

  16.  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. • Try again! • Choose a new question. Penile Urethra

  17. Male Reproduction Q2 Contrast Injection • (i) What type of animal do you think A is from? • Carnivore • Horse • Ruminant/Boar • (ii) Part B is unique to these animals. What is it? • Sigmoid Flexure • Os Penis • (iii) What species is C? • Cat • Dog • (iv) Is it male or female? • Male • Female B A C

  18.  Correct  • Yes! A is from a Ruminant! • Ruminants and Boars have Fibro-elastic penises; as opposed to Musculo-cavernous ones. • Try (ii)! • Choose a new question. Bovine Penis

  19.  Incorrect  • No, A is not from a Carnivore. • Carnivores have Musculo-cavernous penises with an Os Penis. • Try again! • Choose a new question. Canine Os Penis

  20.  Incorrect  • No, A is not from a Horse. • Horses have Musculo-cavernous penises like Carnivores but they do not have an Os Penis. • Try again! • Choose a new question.
