Question | Answer |
O: Iliac crest, posterior surface of sacrum, coccyx
I: Gluteal tuberosity of femur, iliotinial band
A: Prime mover is extension and lateral rotation of thigh
Innervation: inferior gluteal nerve | Gluteus Maximus |
O- superior 1/2 of posterior surface of ilium
I-greater trochanter
A- Prime: Abduction and medial rotation of thigh
Innervation: Superior gluteal nerve | Gluteus Medius |
O: inferior, lateral, posterior surface of ilium
I: greater trochanter
A: Prime: abduction and medial rotation of thigh
Innervation: superior gluteal never | Gluteus Minimus |
O: Pelvic surface of sacrum

O: Inner rim of obturator foramen
I: Greater trochanter
A: Prime:lateral rotation of thigh
Innervation: obturator internus nerve | Obterator Internus |
O: Ischial tuberosity
I: Posterior femor between greater and lesser trochanters
A: Prime: lateral rotation of thigh
Innervation: nerve to quadratus femoris(L5, S1) | Quadratus Femoris |
O: Iliacus- inner surface of ilium & sacrum
I: together on same tendon to lesser trochanter
A: together-flexion of thigh; iliacus-flexion & lateral rotation
Innvercation: iliacus: femoral & lumbar nerves | Iliopsoas |
O: Psoas- bodies & tansverse processes of lumber vertebrae
I: together on same tendon to lesser
trochanter
A: psoas- flexion & lateralrotation of thigh;flexion of vertebral column
Innervation: Psoas: lumber nerves | Iliopsoas |

O: anterior inferior iliac spine & superior margin of acetabulm
I: base of patella via quadriceps tendon(Action is applied to the tibial tuberosity via the patellor tendon)
A: Prime: flexes femur and extends knee
Innervation: Femoral nerve | Rectus Femoris |
