Obturator Externus |
ORIGIN: outer border of the obturator membrane and associated bony borders stabilization of pelvis in sagittal plane |
|
Gluteus Maximus |
ORIGIN: Sacrum (dorsal surface, lateral side), Ilium (gluteal surface, posterior side), sacrotuberous ligament, thoracolumbar fascia INSERTION: upper fibers - IT band (iliotibial tract); lower fibers - gluteal tuberosity |
|
Tensor Fascia Lata |
ORIGIN: Anterior superior iliac spine (ASIS) INSERTION: IT band (iliotibial tract) ACTION: tenses the fascia lata hip joint - int rotation, flexion, abduction |
|
Gluteus Medius |
ORIGIN: Ilium (gluteal surface below the iliac crest and b/t the ant and post gluteal lines) ACTION: whole muscle - abducts and stabilizes (in the coronal/frontal plane) the hip; Ant part - int rotation and flexion of hip; post part - ext rotation and extension of hip |
|
Quadratus Femoris |
ORIGIN: lateral border of the ischial tuberosity INSERTION: intertrochanteric crest of the femur INNERVATION: direct branches from the sacral plexus (L5-S1) |
|
Gluteus Minimus |
ORIGIN: Ilium (gluteal surface below the origin of the glut med) INSERTION: anterolateral surface of the greater trochanter of the femur INNERVATION: Superior gluteal n (L4-S1) ACTION: Whole muscle - abduction and stabilization (coronal/frontal plane) of hip; ant part - int rotation and flexion of hip; post part - ext rotation and extension of hip |
|
Obturator Internus |
ORIGIN: inner border of the obturator membrane and associated bony borders INSERTION: medial surface of greater trochanter of the femur INNERVATION: direct branches from sacral plexus (L5-S1) ACTION: hip - ext rotation, adduction, extension of the hip (sometimes abduction depending on position of hip) |
|
Superior Gemelli |
ORIGIN: Ischial spine INSERTION: medial surface of the greater trochanter of the femur INNERVATION: direct branches from the sacral plexus (L5-S1) ACTION: hip joint - ext rotation, adduction, extension (can do abduction depending on position of the hip) |
|
Inferior Gemelli |
ORIGIN: Ischial tuberosity ACTION: hip joint - ext rotation, adduction, extension (also abduction depending on position of the hip) |
|
Piriformis |
ORIGIN: pelvic surface of the sacrum |
