Pelvic Limb Theory Flashcards
What % of the body weight is beared by the pelvic limb?
45%
What is the function of the pelvic girdle?
Transmit thrust of limb into trunk via the sacroiliac joint
What type of joint attaches the sacrum to the os coxae?
Cartilaginous
Extrinsic muscles (attach limb to axial skeleton) are grouped as?
Sublumbar hypaxial muscles
What 4 muscles make up the sublumbar hypaxial muscles?
Iliopsoas complex, Psoas minor and quadratus lumborum
What are the 4 groups of intrinsic muscles of the hip joint?
Gluteal, deep, medial and caudal
Gluteal intrinsic muscles have what functions?
Hip extension, Limb abduction and medial rotation
Deep muscles (internal obturator, gemelli, quadratus femoris) have what function?
Lateral rotation and hip extensors
Which group of muscles of the pelvic limb are the major hip extensors (biceps femoris, semi membranous, semitendinosus, caudal crural adductor)?
Caudal group
What is the main weight bearing muscle of the pelvic limb?
Quadriceps femoris
What is the important role of the gastrocnemius?
Main hock extensor
What muscles share the Common Calcanean tendon as their common tendon of insertion?
Gracilis, Biceps femoris, semitendinosus
The aorta branches into which two parts before exiting the abdominal cavity?
External and internal iliac artery
List the arterial tree after exiting the body cavity through the inguinal ring
Femoral, Popliteal, Craneal-tibial, dorsal pedal, great metatarsal, digital
What is the pulse palpation site of the pelvic limb named?
Femoral Triangle
What are the borders of the femoral triangle?
Pectineus, caudal sartorius and inguinal ligament (quadriceps laterally)
Describe what is the vascular lacuna
A depression where vesicles come off to form the femoral triangle
What are the 2 superficial veins of the pelvic limb?
Cranial branch of lateral saphenous and medial saphenous
Which saphenous vein is used to draw blood in felines?
Medial saphenous
What are the 4 lymph nodes found in the Pelvic Limb?
Sumblumbar/Iliosacral
Popliteal
Superficial Inguinal
Prefemoral/Subiliac
What lymph node of the pelvic limb drains the last 2 mammary glands?
Superficial inguinal
Which pelvic Limb LN is not always present?
Prefemoral/Subiliac
What are the limits (vertebrae) of the lumbosacral plexus?
L4 to S2
Which nerve innervates the plantar paw?
Tibial n
The dorsal paw is innervated by which nerve?
Fibular n
List the main nerves of the pelvic limb (one branches)
Femoral, Gluteal (craneal and caudal), Obturator, Sciatic - Fibular (common, superficial and deep) and Tibial
Give an example of an autonomous zone used to check nerve function
Pinch dorsal paw, if the dog retracts and flexes the whole limb, the fibular nerve is working along with every other nerve
