Q

Give the arterial interspecies differences

A

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)
