Muscles of the Hip origin insertion action nerve
| Question | Answer |
|---|---|
| Gluteus Maximus origin | posterior sacrum illium, superior gluteal line of ilium |
| Gluteus Maximus insertion | gluteal tuberosity of femur iliotibial tract |
| Gluteus Maximus Actions | Extension of femur at hip,lateral rotation of extended hip |
| Gluteus Maximus nerve | Inferior gluteal nerve |
| Gluteus Medius origin | illiac crest,ilium between superior and middle gluteal lines |
| Gluteus Medius insertion | greater trochanter of femur |
| Gluteus Medius actions | hip abduction,medial rotation of femur at hip |
| Gluteus Medius nerve | superior gluteal nerve |
| Gluteus Minimus origin | posterior ilium -between middle and inferior gluteal lines |
| Gluteus Minimus insertion | anterior surface of greater trochanter of femur |
| Gluteus Minimus actions | hip abduction, medial rotation of femur at hip |
| Glutus Minimus nerve | superior gluteal nerve |
| Deep 6 lateral rotators origins 1.Piriformis 2.Gemellus Superior 3.Obturator Internus 4.Gemellus Inferior 5.Obturator Externus 6.Quadratus Femoris | Anterior sacrum, ischium, obturator foramen |
| deep 6 lateral rotators insertion | greater trochanter of femur |
| deep 6 lateral rotators action | lateral rotation of femur at hip |
| deep 6 lateral rotators nerve | branches from sacral plexus (obturator externus supplied by obturator nerve) |
| Psoas major origin | lumbar vertebrae T12-L5 |
| Iliacus origin | inner surface of ilium |
| Psoas major and iliacus (iliopsoas) insertion | lesser trochanter of femur |
| Psoas major and iliacus (iliopsoas)action | flexion of femur at hip joint,if thigh is fixed, flexion of truck at hip joint |
| Psoas major and iliacus (iliopsoas) nerve | psoas major -L2, 3 directly iliacus -femoral nerve |
