femoral artery
external iliac artery passes under iguinal ligament and becomes femoral artery
as it branches the deep femoral artery (profunda femoris) passes posteriorly to supply to posterior thigh
it passes through adductor canal, through adductor hiatus, passing posterior through femoral intercondular fossa and becomes popliteal artery (then into leg)
adductor canal (subsartorial canal)

deep to sartorius and in front of adductor muscles
adductor canal borders
anterior & lateral: vastus medialis

posterior: adductor longus and magnus
adductor canal start & finish
