What is the function of the Gluteus Medius?
abduction and medial rotation of the thigh; helps in lateral rotation and flexion of the hip; keeps the pelvis level when the opposite leg is raised
What is the innervation of the Gluteus Medius?
superior gluteal nerve (L5-S1)
What is the function of the Gluteus Minumus?
abduction and medial rotation of the thigh; helps in lateral rotation and flexion of the hip; keeps the pelvis level when the opposite leg is raised (same as medius)
What is the innervation of the Gluteus Minimus?
superior gluteal nerve (L5-S1)
What is the function of the Piriformis?
lateral rotator and abductor of the thigh, keeps the femus head in the acetabulum
What is the innervation of the Piriformis?

nerve to the obturator internus (L5-S1)
What is the function of the quadratus femoris?
lateral rotation and adduction of the hip, the lateral rotators of the thigh are stronger than the medial rotators, and control balance
What is the innervation of the quadratus femoris?
supplied via the nerve to the quadratus femoris
