Q
Gluteus Maximus
A
O= gluteal surface of ilium, lumbar fascia, sacrum, sacrotuberous lig I= Gluteal tuberosity of femur and ITT A= Lateral rot, extension, supports extended knee In= Inf gluteal nerve (L5-S2)
2
Q
Gluteus Medius
A
O= Greater surface of ilium between ant+post gluteal lines I= Greater trochanter of femur A= Abduction, medial rot In= Sup gluteal nerve (L4-S1) More lateral and below Max
3
Q
Gluteus Minimus
A
O= Gluteal surface of ilium (between ant+inf gluteal lines) I= Greater trochanter A= Abduction, medial rot In= Sup gluteal nerve (L4-S1)
4
Q
Piriformis
A
Passes from greater sciatic foramen to less one
O= Sacrum
I= Greater Trochanter
5
Q
Obturator Internus
