It is inserted between the two layers of the [[iliotibial band]] of the fascia lata about the junction of the middle and upper thirds of the thigh. ==Function== The Tensor fasciæ latæ is a tensor of the fascia lata; continuing its action, the oblique direction of its fibers enables it to abduct the thigh and to rotate it inward (medial rotation). In the erect posture, acting from below, it will serve to steady the pelvis upon the [[head of the femur]]; and by means of the [[iliotibial band]] it steadies the [[condyles of the femur]] on the articular surfaces of the tibia, and assists the [[Glutæus maximus]] in supporting the knee in the extended position. ==Additional images== <gallery> Image:Gray235.png|Right hip bone.
