Arteries - External iliac artery

12 important questions on Arteries - External iliac artery

What regions of the hindlimb does the external iliac artery supply to?

Legs and thighs

How does the external iliac artery supply to the legs?

Branches off to femoral artery, then distal caudal femoral

How does the external iliac artery supply to the thighs?

Branches off to deep femoral, and becomes lateral and medial circumflex femoral past the pudendoepigastric trunk

When does the femoral artery become the popliteal artery?

Slight above the stifle, still in the femur, at the adductor hiatus

When does the popliteal artery become cranial and tibial arteries?

Distal to the stifle. The cranial tibial arteries supply the extensors, and the caudal tibial arteries supply the flexors.

Which branches of the external iliac artery supplies the craniolateral muscles?

Cranial tibial from popliteal (femoral), saphenous from femoral.

What supplies blood to the digital extensors?

Cranial tibial artery from popliteal artery

What supplies blood to the caudal group of the calves/hock?

Cranial tibial, popliteal, saphenous artery

What are all the vessels used in the hindlimb of a dog?

1. Aorta
2. External iliac artery
  • Deep femoral artery
    • Deep circumflex artery
  • Femoral artery
    • Saphenous artery
    • Popliteal artery
      • Cranial artery
        • Dorsal pedal to digital

3. Internal iliac artery
  • Caudal gluteal
    • Cranial gluteal

What vessels supply to the digits of horses?

Medial & lateral plantar arteries: Main continuation into the digit (common digital)
Medial & lateral plantar digital arteries: Main arteries running down the digit
Dorsal metatarsal III -> Interdigital artery: Dorsal contribution
Terminal arch: terminal structure

What vessels supply to the hooves?

The terminal arch from the anastomosis of the medial and lateral plantar digital arteries leads to the solar circumflex being supplied

What vessels supply to the digits of dogs?

Caudally
- Caudal branch of saphenous -> Medial and lateral plantar -> digitals

Dorsally
- Cranial tibial and cranial branch of saphenous -> Dorsal pedal over tarsus -> dorsal metatarsals and digitals
