Tensor Fasciae Latae

Muscle Origin

Iliac crest to tibia by way of the iliotibial tract.

Outer surface of the anterior iliac crest, between the tubercle of the iliac spine. A thick fascia covers the outer surface of the muscle, making it appear to be sandwiched between the layers of fasciae latae.

Insertion

Iliotibial tract.

Insertion is by the iliotibial band anterior surface of the lateral condyle of the tibia. The iliotibial tract or iliotibial band (also known as Maissiat’s band or IT Band) is a longitudinal fibrous reinforcement of the fascia lata. The action of the ITB and its associated muscles is to extend, abduct, and laterally rotate the hip. In addition, the ITB contributes to lateral knee stabilization. Wiki

Action

Flexes and abducts thigh.

Assists with flexion of the thigh at the hip, assists with adduction of the thigh at the hip. The muscle assists in keeping the balance of the pelvis while standing, walking, or running.

Innervation – Nerve control

Superior gluteal nerve.

The superior gluteal nerve is a nerve that originates in the pelvis and supplies the gluteus medius, the gluteus minimus, and the tensor fasciae latae muscles. Wiki

Artery

Primarily lateral circumflex femoral artery, superior gluteal artery.

Antagonist muscles

Gluteus maximus, Adductor magnus (posterior part).

The adductor magnus is a large triangular muscle, consisting of two parts, situated on the medial side of the thigh. The Gluteus Maximus muscle, one in each buttock, moves the thigh.
