Anatomical terminology

In anatomy, the thigh is the area between the hip (pelvis) and the knee. Anatomically, it is part of the lower limb.[1]

The single

ball and socket joint at the hip, and a modified hinge joint at the knee.[2]

Structure

Bones

The

hip joint, while the distal part of the femur articulates with the tibia and patella forming the knee. By most measures, the femur is the strongest bone in the body. The femur is also the longest bone in the body.[3]

The femur is categorised as a

epiphyses, the lower extremity and the upper extremity of femur, that articulate with adjacent bones in the hip and knee.[4]

Muscular compartments

In cross-section, the thigh is divided up into three separate compartments, divided by fascia, each containing muscles. 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.

Anterior compartment muscles of the thigh include

vastus lateralis
.

Posterior compartment muscles of the thigh are the

biceps femoris
.

Medial compartment muscles are

.

Because the major muscles of the thigh are the largest muscles of the body, resistance exercises (strength training) of them stimulate blood flow more than any other localized activity.[5]

Blood supply

Main blood vessels of the thigh.[6]

The arterial supply is by the femoral artery and the obturator artery. The lymphatic drainage closely follows the arterial supply and drains to the lumbar lymphatic trunks on the corresponding side, which in turn drains to the cisterna chyli.

The deep venous system of the thigh consists of the

varicose veins).[7]

Clinical significance

Thigh weakness can result in a positive

Gowers' sign on physical examination.[8]

Thigh injury

tendinitis
.

patellofemoral pain) is a direct consequence of the kneecap rubbing against the end of the thigh bone (femur). Tight hamstrings and weak thigh muscles, required to stabilize the knee, increase the risk of developing of runner's knee.[9]

Society and culture

Western societies generally tolerate clothing that displays thighs, such as

styles often display thighs as well. Professional dress codes may require covering up bare thighs.

Many

Islamic countries
disapprove of or prohibit the display of thighs, especially by women.

Strategic covering or display of thighs is used in popular fashion around the world, such as

zettai ryoiki
.
