In [[human anatomy|humans]] the '''thigh''' is the area between the [[pelvis]] and the [[knee]]. Anatomically, it is part of the [[Human leg|lower limb]].

The single [[bone]] in 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 joint]] at the [[hip]], and a condylar joint at the knee.

In cross-section, the thigh is divided up into three [[fascial compartment]]s. These compartments use the femur as an axis, and are separated by tough [[connective tissue]] membranes (or [[septum|septa]]). Each of these compartments has its own [[blood]] and [[nerve]] supply, and contains a different group of [[muscle]]s.

In humans the thigh is the area between the pelvis and the knee. Anatomically, it is part of the lower limb.

The single bone in 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 joint at the hip, and a condylar joint at the knee.

Fascial compartmentsEdit

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 tissue membranes (or septa). Each of these compartments has its own blood and nerve supply, and contains a different group of muscles.

Blood vesselsEdit

The arterial supply is by the femoral artery and 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).

Thigh weaknessEdit

Thigh weakness can result in a positive Gowers' sign on physical examination.
