BIOM20002 Lecture Notes - Lecture 27: Vena Comitans, Varicose Veins, Thrombus
Document Summary
Major arteries begin at the junction of the lower limb & pelvis (abdomen). Right and left iliac artery --> bifurcates again into internal (supplies pelvic viscera) and external iliac artery (leads to femoral artery (+ profunda femoris)) External iliac runs under inguinal ligament and becomes femoral artery. Femoral artery comes down anteriorly then courses medially to reach posterior compartment (for protection). Profunda femorus: deep branch of the femoral artery. Can be ruptured if you break your hip. Lose blood supply to head of femur anastomoses between profunda femoris artery branches. Posterior tibial artery comes through tarsal tunnel to supply blood to foot. Superficial veins dorsal venous arch great saphenous: on medial side small saphenous: on lateral/posterior side (all in superficial fascia) Lymphatics drainage follows superficial veins of the lower limb: inguinal nodes: superficial lymph drains into here. Both lower limbs drain to thoracic duct on the left side. Nodes in clavicular region are the final sentinel nodes.
