Document Summary

The major arteries begin at the junction of the lower limb and pelvis. The aorta splits into 2 common iliac arteries in the pelvis which then splits again into 2 again (internal + external iliac arteries) The inguinal ligament is just a folding of the abdominal muscles as they end. Once artery passes this, becomes known as femoral artery. Femoral artery main blood supply for lower limbs. Starts of anterior however quickly moves medially and towards the flexor/posterior surface (more protected) The profunda femoris supplies posterior compartment of lower. The profunda femoris branch into the neck of femur this is why limb fracture of femur head is so traumatic. As it passes behind the knee, the artery becomes known as the popliteal. Lots of collateral branching around the knee joint so that circulation is not cut off. As it enters the lower leg, branches into anterior and posterior tibial. Passes through the tarsal tunnel to reach foot plantar arteries.
