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 I: Superior border of greater trochanter A: Prime: lateral rotation of thigh Innervation: nerve to obturator internus | Piriformis |
O: ischial spine I: greater trochanter via obturator internus tendon A: Prime: lateral rotation of thigh Innervation: nerve to obturatir internus | Superior Gemellus |
O: Ischial tuberosity I: Greater trochanter of thigh A: Prime: Lateral rotation of thigh Innervation: branch of quadrtus femoris nerve | Inferior Gemellus |
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: Pectineal line of pubis I: Iliotibial band A: prime: medial rotation & abduction of thigh Innervation: Superior gluteal nerve | Pectineus |
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 |
