Proximal attachment – posterior surface of sacrum and sacrotuberous ligament
Distal attachment –gluteal tuberosity of femur
Function – extension and lateral rotation of hip
Superficial 3/4ths
Proximal attachment – posterior to posterior gluteal line of ilium. Posterior aspect of sacrum. Sacrotuberous ligament.
Distal attachment – anterior surface of lateral tibial condyle via iliotibial band
Function – extension of hip and knee, stabilises pelvis on thigh; contracts during late swing and early stance  decelerates flexion at the hip and accelerates extension
