Muscular compartments. Main article: Fascial compartments of thigh. 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).

In general, muscles located in the hip region will move the thigh, and muscles located in the thigh will move the leg. Most of the thigh muscles are contained within two large groups of muscles referred to as the quads, which extend the leg at the knee and the hamstrings, which flex the leg at the knee.

Human leg. The human leg, in the general meaning, is the entire lower extremity or limb of the human body, including the foot, thigh and even the hip or gluteal region. However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle.

The iliotibial band is a strong, thick band of fibrous tissue that runs along the outside of the leg. 1  The IT band starts at the hip and runs along the outer thigh and attaches on the outside edge of the shin bone (tibia) just below the knee joint. The band works with the quadriceps (thigh muscles) to provide stability to the outside of the knee joint during movement.

The IT band is often the hidden cause of many people's outer knee or hip pain. Iliotibial band friction syndrome can cause a nagging, dull ache, or flare into a sharp, acute pain felt at a specific spot on the outside (lateral aspect) of the knee and lower thigh.

The medial thigh muscles. The muscles of the medial part of the thigh include muscles that bring the thigh toward the midline and rotate it: Adductor longus: This muscle originates on the pubis and inserts onto the middle of the linea aspera of the femur. It’s innervated by the obturator nerve and adducts the thigh.

These muscles are located in the posterior compartment of the thigh, which is the back side. The biceps femoris is a double-headed muscle, hence the prefix bi. The long head originates from the pelvic girdle, while the short head originates from the femur. Both heads insert on the fibula and tibia of the leg.

In summary, most muscles in the anterior compartment of the thigh extend the leg, while muscles in the posterior compartment of the thigh flex the leg. The hamstrings are leg flexors, and include three muscles located in the posterior compartment. They are the biceps femoris, semitendinosus and semimembranosus.

The thigh muscles don’t just move your legs. They have a lot to do with how your hips move. In clinical anatomy the thigh muscles are divided into three groups: Anterior muscles extend your legs and flex your thighs. Medial muscles adduct and rotate your thigh, and posterior flex your leg and extend your thigh.

Muscles are located in the posterior compartment of the thigh, which is the back side. The thigh muscles are located in the posterior compartment of the thigh, which is the back side.
