Which vessels supply the adductors of the pelvic limb? (gracilis, adductor, pectineus)
proximal and middle caudal femorals
Which nerve innervates the adductors of the pelvic limb?
obturator
What muscles are innervated by obturator n?
external obturator, pectineus, gracilis, and adductor
Caudal rectal n is a branch off of ?
Pudendal nerve
What does the caudal rectal nerve innervate?
the external anal sphincter
What muscles does the femoral nerve innervate?
sartorius, ilospoas, quadriceps (all 4 heads)
What actions cannot be done if there is damage to the femoral nerve?
extension of stifle, p will be unable to bear weight on hind leg
Which nerve innervates flexors and extensors of the stifle and extensors of the hip?
sciatic
What muscles does sciatic nerve innervate?
internal obturator, gemelli, quadratus femoris, biceps femoris, semitendinosus, semimembranosus
What are 2 main branches off of sciatic n?
tibial nerve, common fibular nerve
Which nerve innervates the flexors of the tarsus and extensors of digits?
Common Fibular n
What muscles does the common fibular n innervate?
cranial tibial, fibularis longus, long digital extensors
Innervation and Supply to the flexors of tarsus and extensors of the digits?
Common fibular NERVE
Cranial tibial ARTERY
Which nerve innervates the rotators of the stifle, extensors of the tarsus, and flexors of the digits?
Tibial
What muscles does the Tibial nerve innervate?

Which nerve innervates the middle and deep gluteals?
cranial gluteal n
What is the sole innervation to the superficial gluteal m?
caudal gluteal n
Which artery supplies the middle and deep gluteals?
cranial gluteal artery
What does the caudal gluteal artery supply?
superficial and middle gluteals, the rotators of the hip, and the adductor muscle
-divides into branches which supply the biceps femoris, semitendinosus and semimembranosus muscles
the external iliac artery continues as the ? artery after passing through the abdominal wall
femoral
Which nerve, artery and vein can be exposed in the femoral triangle?
femoral artery and vein, and the saphenous nerve
What does the lateral circumflex femoral artery supply?

What does the proximal caudal femoral artery supply?
pectineus, adductor, and gracilis
What does the middle caudal femoral artery supply?
adductor and semimembranosus
What does the distal caudal femoral artery supply?
biceps femoris, semimembranosus, semitendinosus, gastrocnemius, and the digital flexors
What does the popliteal artery supply?
the stifle, gastrocnemius, and popliteus muscles
What does the caudal cutaneous femoral nerve supply?
the skin on the proximal caudal half of the thigh
What is the main pelvic limb arterial channel?
External iliac -> femoral -> popliteal -> cranial tibial -> dorsal pedal
What does the medial circumflex femoral artery supply?
adductor, vastus medialis, obturators, hip joint capsule, semimembranosus
Deep femoral branches into ??
Medial circumflex femoral, external pudendal & caudal epigastric
