Question | Answer |
Hip Flexors - Psoas Major | Large, thick muscle deep in abdomen. From vertebral bodies and discs at T12-T5 to the inguinal ligament and anterior part of hip joint capsule. |
Hip Flexors - Iliacus | Primarily a hip flexor and stabilizer. Poor flexibility may increase lumbar lordosis, anterior pelvic tilt and a hip-flexed posture. |
Hip Flexors - Tensor Fascia Latae | From anterior iliac crest to the IT band, producing abduction, flexion and medial rotation of the thigh. |
Hip Flexors - Iliotibial band | From iliac crest to purerolateral tibia and head of fibula. |
Sartorius | Longest Muscle of body running from ASIS to superomedial tibia producing flexion, lateral rotation and abduction of femur. |
Rectus Femoris | 2 joint muscle, crossing the hip and knee |
Hip Extensors - Gluteus Maximus | Thigh extension from 45 degrees down to 0 degrees of flexion. |
Hip Extensors - Biceps Femoris, Semimembranosis and Semitendonosis | All Part of hamstrings |
Lateral Hip Rotators | Periformis, Obturator intermus, Obturator externus, Gemellus inferior, Gemellus superior, Quadratus femoris |
Medial Hip Rotators | Gluteus minimus, Gluteus medius - anterior fibers, Tensor Fascia Latae, Gracilis |
Hip Adductors - Adductor magnus | Largest and strongest of adductors |
Hip Adductors - Adductor Brevis | Hip adduction |
Hip Adductors - Adductor longus | Anterior to adductor brevis |
Hip Adductors - Pectineus | From lateral pubis to pectineal line connecting lesser trochanter to linea aspera |
Hip Adductors - Gracilis | Long, thin superficial hip adductor |
Hip Abductors - Gluteus Medius | Superior to gluteus maximus, abducts and medially rotates thigh. Secondary job is hip flexion |
Hip Abductors - Gluteus Minimus | Anterior to gluteus medius, reinforces action of anterior portion of gluteus medius (abduction and flexion of hip) |
Hip Abductors - Tensor Fascia Latae | From anterior iliac crest to the IT band producing abduction, flexion and medial rotation of thigh |
Sartorius | Flexes, laterally rotates and abducts hip |
