pelvic limb arterial supply

abdominal aorta → external iliac → femoral → popliteal → cranial tibial → dorsal pedal → perforating metatarsal → deep plantar arch → plantar metatarsal arteries

plantar metatarsal arteries

main source of blood supply to digits

superficial venous system

lateral saphenous vein and medial saphenous vein

deep venous system

deep femoral vein and femoral vein

constant lymph nodes

popliteal, superficial inguinal, medial iliac

palpable lymph nodes

popliteal and superficial inguinal

inconstant lymph nodes

iliiofemoral/deep inguinal, femoral

where is iliofemoral/deep inguinal lymph node found?

at entrance of femoral triangle

terminal lymph node

medial iliac

what nerve do cranial and caudal gluteal nerves come from?

lumbosacral trunk of L7

innervation of femoral, obturator, cranial gluteal, caudal gluteal, sciatic, common peroneal, tibial, pudendal

• iliopsoas, quadriceps, sartorius

• external obturator, pectineus, gracilis, adductor

• middle glutal, deep gluteal, tensor fascia latae

• superficial gluteal, (middle gluteal)

• biceps femoris, semimembranosus, semitendinosus

• peroneus longus, lateral digital extensor, long digital extensor, cranial tibial

• gastrocnemius, popliteus, superficial digital flexor, deep digital flexor

• caudal rectal, external anal sphincter
