Caption = Diagram of the human thigh bone
In humans the thigh is the area between the
pelvisand the knee. Anatomically, it is part of the lower limb.
bonein the thigh is called the femur. This bone is very thick and strong (due to the high proportion of cortical bone), and forms a ball and socket jointat the hip, and a condylar joint at the knee.
In cross-section, the thigh is divided up into three
fascial compartments. These compartments use the femur as an axis, and are separated by tough connective tissuemembranes (or septa). Each of these compartments has its own bloodand nervesupply, and contains a different group of muscles.

The arterial supply is by the
femoral arteryand the obturator system. The lymphatic drainage closely follows the arterial supply.
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).
