Deep Hip Outward RotatorsThe deep hip outward rotators muscle group is made of 6 muscles. They are obturator internus, obturator externus, piriformis, gemellus superior, gemellus inferior, and quadratus femoris. They all act as synergists to each other, meaning they all assist each other in their movements. Below are the study aids for massage school.
Obturator InternusOrigin is obturator membrane.Insertion is greater trochanter. Action--laterally rotates hip.
Obturator ExternusOrigins are obturator membrane, superior pubic ramus, and inferior pubic ramus.Insertion is greater trochanter. Action--laterally rotates hip.
PiriformisOrigin is anterior sacrum.Insertion is greater trochanter. Actions--laterally rotates hip and abducts the hip. This is the largest of the lateral rotator muscles.
Gemellus SuperiorOrigin is ischial spine.Insertion is greater trochanter. Action--laterally rotates hip.
Gemullus InferiorOrigin is superior ischial tuberosity.Insertion is greater tuberosity. Action--laterally rotates hip.
Quadratus FemorisOrigin is lateral ischial tuberosity.Insertion is greater trochanter. Action--laterally rotates hip.
