Tibial n
ventral branches of the lumbar and sacral spinal n.n.
lumbosacral plexus
Parent: Aorta
Exits the abdominal cavity through the ‘vascular lacuna’ (into the pelvic limb)
External iliac a
Located between the caudal border of the aponeurosis of the external abdominal oblique (inguinal ligament) and the pelvis
Vascular lacuna
Parent: External iliac a
Only branch off the external iliac a within the abdominal cavity
Deep femoral a
Parent: Deep femoral a
Common trunk for:
-external pudendal a
-caudal epigastric a
Pudendoepigastric trunk
Parent: Pudendoepigastric trunk
Supplies: Gracilis m, external repro organs
*Passes through the inguinal canal
External pudendal a
Parent: Pudendoepigastric trunk
Supplies: caudal aspect of Rectus abdominus m
Caudal epigastric a
Continuation of Deep femoral a
Supplies: Adductor m
*Passes through inguinal ring
Medial circumflex femoral a
Continuation of External iliac a 7 branches: 1. Superficial circumflex iliac a 2. Lateral circumflex femoral a 3. Proximal caudal femoral a 4. Saphenous a - Cranial branch - Caudal branch 5. Descending genicular a 6. Middle caudal femoral a 7. Distal caudal femoral a
Femoral a
