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.
Muscles - There are two kinds of muscle that are part of the musculoskeletal system - skeletal and smooth. The third type of muscle, cardiac, is not part of the musculoskeletal system. Skeletal muscles are bundles of contractile fibers. The action of contracting muscle is what moves various parts of the body.
