The gluteal group of muscles consists of 3 muscles: Gluteus Maximus, Gluteus Medius and Gluteus Minimus. Gluteus is Greek for rump. Maximus is the largest of the muscles and Minimus the smallest. The role of the Gluteus maximus is different from the medius and minimus muscles because of their attachment points.
The gluteus medius muscle is located at the outer part of the hip. The gluteus minimus is the smallest of the gluteal muscles and is located immediately beneath the gluteus medius. Together, these muscles work to straighten the hip during activity, stabilize the pelvis and assist with outer movements of the hip.
