Main veins of the lower limb

This tutorial explores the venous system of the lower limbs, focusing on deep, superficial, and perforating veins. It details the anatomy and function of these veins, including the plantar and dorsal veins, fibular, tibial, popliteal, and femoral veins. The tutorial also covers the great and small saphenous veins, and discusses varicose veins, their symptoms, and treatment options. The session concludes with a summary of the key points covered.
