Practical topic 37

Question 1

Arterial blod supply of the kidney

Answer 1

• A. renalis
  
  • Divides into A. interlobares at hilus renalis
    
    • Divides again into A. arcuatae, curving over the medullary pyramis
      
      • Gives off A. interlobulares
• ​​​capillary plexus around renal tubules

Question 2

Which vein drains blood from the kidneys?

Answer 2

• v. renalis
  
  • Divides into V. interlobares at hilus renalis
    
    • Divides again into V. arcuatae, curving over the medullary pyramis
      
      • Gives off A. interlobulares
• ​​​Capillary plexus around renal tubules

Question 3

Which vessel is the right kidney associated with?

Answer 3

• V. cava
• Lies further cranially than the left kidney

Question 4

Which vessel is the left kidney associated with?

Answer 4

• Aorta abdominalis
• Lies more caudal than the right kidney

Question 5

How is the right kidney connected to the caudate process​ of the liver?

Answer 5

By lig. hepatorenale

Question 6

Give the parts of the ureter, and localization

Answer 6

• Pars abdominalis
  
  • Lies on m. psoas major et minor
  • Crosses the large terminal branches of the aorta and vena cava caudalis ventrally
• Pars pelvina
  
  • Enters the genital fold/broad ligament
  • Male: crosses dorsal surface of ductus deferens
  • Female: crosses a. uterina

Question 7

Which vessels are the ureter supplied by?

Answer 7

• Branches of a. renalis
• a. vesica cranialis
• a. vaginalis / a. prostatica

Question 8

Parts of the urinary bladder

Answer 8

• Apex vesicae
• Corpus vesicae
• Cervix vesicae
  
  • Leading to urethra

Question 9

What is the apex and cervix vesicae surrounded by?

Answer 9

M. sphincter vesicae

Question 10

Give the ligaments of the bladder, and their suspensions

Answer 10

• Lig. vesicae medianum
  
  • ​Small median fold between the pelvic floor and facies ventralis
• Lig. vesicae laterale
  
  • ​Left + right peritoneal fold attaches to the dorsolateral wall in males
• Lig. teres vesicae
  
  • ​Super tiny
  • Cranial free edge of the lateral ligament

Question 11

Give the invaginations

Answer 11

• Excevatio pubovesicalis
• Vesicogenitalis
• Rectogenitalis

Question 12

Where does the urethra begin and end in males?

Answer 12

• Start: ostium urethra interna
• End: Ostium urethrae externum at the tip of the penis

Question 13

Give the divisions of the pars urethra in males

Answer 13

• Pars pelvina
  
  • ​Preprostatic part (only urine)
    
    • Short, proximal part, extending from internal orifice to entrance of ductus deferens (ends at colliculus seminalis)
  • Prostatic part
    
    • ​Transport urine and semen
    • Colliculus seminalis - point where urinary and gential ducts join
• Pars penia/pars spongiosa
  
  • ​Accessory genital glands group around this part
  • Pars spongiosa: Within the penis

Question 14

Give the blood supply of the ureter

Answer 14

• A. renalis → r. uretericus
• A. vaginalis / a. prosatica

Question 15

Give the blood supply of the bladder

Answer 15

• A. umbillicus → a. vesicae cranialis
• A. epigastrica caudalis → a. vesicae mediae
• A vaginalis / a. prostatica → a. vesicae caudalis (to cervix)

Question 16

Give the blood supply of the urethra

Answer 16

• A. vaginalis / a. prostatica → r. urethralis
• A. pudenda interna → a. urethralis
• A. vesicae caudalis → r. urethralis

Question 17

What is the ductus deferens a continuation of?

Answer 17

Epididymis duct

Question 18

What does the ductus deferens connect?

Answer 18

Epididymis with the pelvic part of the urethra

Question 19

What does the spermatic cord consists of?

Answer 19

• A. testicularis
• V. testicularis
• Lymphatics
• Testicular plexus of nerves
• Bundles of SM (m. cremaster)
• Ductus deferens (in the mesoductus deferens)

Question 20

What is the prostatae gland fused with?

Answer 20

Pelvic urethra

Question 21

Give the parts of the prostatae gland

Answer 21

• Capsula prostatae
  
  • ​Encloses the prostatae gland
• Corpus prostatae:
  
  • ​Compact
    
    • Pars disseminate prostatae - forms glandular layer in the urethral wall
• Divided into lobus sinistra et dextra, by median groove

Question 22

Give the blood supply of the prostatae gland

Answer 22

• A. prostatica (ex. a. pudenda interna, ex. a. iliaca interna)
  
  • Runs caudally along the pelvic peritoneum in the direction of the prostatae
    
    • A. ductus deferentis
    • R. urethralis
