Question 1

Ductus deferens

Answer 1

• Continuation of the ductus epididymis, connects it to the pelvic part of the urethra
• Travels with the testicular vessels and nerves
• Forming the spermatic cord - Enclosed in the mesoductus deferens
• Passes through the inguinal canal - Enters the genital fold
• Uterus masculinus: remnant of the paramesonephric ducts
• Perforates the prostate gland

Ampulla ductus deferentis (Ø su)

• Terminal part - Contains glands
• Eq + ru: joins the excretory duct of the vesicular glands  ductus ejaculatorius -
• Sus: ductus deferens and vesicular gland opens separately
• Ca: no vesicular gland

Colliculus seminalis

• Proximal part of the urethra - Seminal hillock

Ductus ejaculatorius

• Joining of the deferent duct and the excretory duct - Normal in Eq and Ru

Plica genitalis

• horizontal sheet of peritoneum inserted between the rectum and bladder

Question 2

What are the male accesory glands?

Answer 2

Gl. vesicularis

Gl. prostata

Gl. bulbourethralis

Question 3

Which animals have ampulla ductus deferentis?

Answer 3

Eq, Ru and Ca

Question 4

What animals have which glands?

Answer 4

The dog only has the prostate gland. The others have all the three glands

• known as cowpers glands
  gl. vesicularis, gl, prostat, gl, bulbourethralis

Question 5

Which glands are paired?

Answer 5

gl. vesicularis and gl. bulbourethralis

Question 6

What are the two parts of the prostate?

Answer 6

corpus prostata

pars desseminta (ø eq)

Question 7

Where can ductus excretorius be found?

Answer 7

in glandulae vesicularis

Question 8

structures of prostata

Answer 8

Ru: small ru only has pars desseminta bull has both, compact is small

Eq: only corpus prostatae

Ca: pars desseminta is vestigial, corpus prostate (compact) is large and globular surrounds the urethra almost completley Facies ventralis et dorsalis

Corpus prostatae

At the beginning of the urethra - Compact

Pars disseminata prostatae

• Disseminate part
• Diffusely spread within the wall of the pelvic urethra
• Few lobules in Car Lobus dexter et sinister

Ca: partially divided by a groove

Isthmus prostatae (eq)

• Lies between the lobes, across the dorsal surface of the neck of the urinary bladder

Parenchyma

• Glandular substance

Ductuli prostatici

• Prostatic ductules
• Many small ducts that opens into the urethra Capsula prostatae
• Contains smooth muscle
• Covers the prosttate

Question 9

where does ductus gl. bulbourethralis lead?

Answer 9

pars penila of urethra

Question 10

where does ductuli prostaici open?

Answer 10

into urethra
