  • gross anatomy: 
    • thick flat sheet of muscle sloping from the pelvis down across the buttock 
    • fan shaped muscle with posterior third lying deep to the posterior recess of the ischioanal fossa 
  • action
    • powerful extensor of flexed femur at hip joint
    • lateral stabilizer of hip joint
    • lateral stabilizer of the extended knee joint
      • by tightening the iliotibial tract 2
    • lateral rotator of the thigh
    • abduction at the hip (upper fibers)
  • arterial supply: superior and inferior gluteal arteries
  • innervationinferior gluteal nerve (L5, S1, S2)
    • ​between the muscle and ischial tuberosity (ischiogluteal bursa)
    • between the muscle and greater trochanter (trochanteric bursa)
    • between the msucle and upper part of the vastus lateralis (gluteofemoral bursa)
  • antagonist
  • variants
