{"Image ImageDescription": "Anterior compartment muscles of the thigh include pectineus, sartorius, and the four muscles that comprise the quadriceps muscles- rectus femoris, vastus medialis, vastus intermedius and vastus lateralis, 1903. From 'Surgical Anatomy: The Treatise of the Human Anatomy and Its Applications to the Practice of Medicine and Surgery, Volume III' (1903). The arterial supply is by the femoral artery and the obturator artery. The deep venous system of the thigh consists of the femoral vein, the proximal part of the popliteal vein, and various smaller vessels; these are the site of proximal deep venous thrombosis. The venae perfortantes connect the deep and the superficial system, which consists of the saphenous veins (the site of varicose veins). (Photo by VintageMedStock/Getty Images)"}
