Answer 2

Question 3

Give the venous system

Answer 3

Question 4

Give the arterial interspecies differences

Answer 4

A. interossea communis

• A. inerossea cranialis
  
  • R. inerosseus (ø eq)
  • Ca: r. carpeus dorsalis forms the continuation of r. inerosseus
• A. interossea caudalis
  
  • Ca:
    
    • Gives off r. carpeus palmaris
    • A. interossea caudalis continues at r. palmaris
  • Eq: no distal interosseus space → no interosseus ramus → r. palmaris originates from a. mediana
• A. ulnaris (ca)
  
  • Ca: arisesd from a. interossea communis

A. mediana

• A. radialis proximalis (eq)
• R. palmaris (eq)
• A. digitalis palmaris communis II (eq)
  
  • A. digitalis (palm. propria III) lateralis
  • A. digitalis (palm. propria III) medialis
    
    • ​Rr. dorsales phalanges proximale
    • Rr. dorsales phalanges mediale
    • Rr. dorsales phalanges distale
    • Rr. palares
      
      • ​Arcus terminalis

Arcus palmaris profundus:

• R. profundus
  
  • Ca: ex. r. palmaris ex. a. interossea caudalis
    
    • ​→ Aa. metacarpeae palmares I-IV
  • Eq: ex. r. palmaris ex a. mediana
    
    • ​→ Aa. metacarpeae palmares II et III

Arcus palmaris superficialis

• Eq: not common

Rete carpi dorsales

• R. carpeus dorsalis
  
  • Ca: ex. a. radialis
  • Eq: ex a. radialis proximalis
• R. interosseus (ø eq)
  
  • Ca: ex. a. interossea cranialis/caudalis
• A. ulnaris (ca)
• A. collateralis ulnaris (eq, ru)
• A. transversa cubiti (eq)
• R. carpeus dorsale
  
  • Eq: ex. a. interossea craniale
    
    • ​Ca: → aa. metacarpeae dorsale I-IV
    • Eq: → aa. metacarpeae dorsale II et III
• Aa. digitales dorsales communis I-IV (ca)
  
  • From r. lateralis ex a. antebrachialis superficialis
• Rr. dorsales phalangis proxinalis, media et distalis (eq)
