Information about Thigh

MeSH Thigh
Dorlands/Elsevier t_09/12804725
In humans the thigh is the area between the pelvis and buttocks 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 compartments

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 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 veins (the site of varicose veins).

Thigh weakness

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

In human anatomy, the knee is the lower extremity joint connecting the femur and the tibia. Since in humans the knee supports nearly the entire weight of the body, it is the joint most vulnerable both to acute injury and to the development of osteoarthritis.
