In [[human anatomy|humans]] the '''thigh''' is the area between the [[pelvis]] and [[buttock]]s 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.

==Fascial compartments==
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.

* [[Medial fascial compartment of thigh]]
* [[Posterior fascial compartment of thigh]]
* [[Anterior fascial compartment of thigh]]

==Blood vessels==
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 vein]]s (the site of [[varicose vein]]s).

==Thigh weakness==
Thigh weakness can result in a positive [[Gower's sign]] on physical examination.
