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 buttocks are formed by the masses of the gluteal muscles or glutes (the gluteus maximus muscle and the gluteus medius muscle) superimposed by a layer of fat.The superior aspect of the buttock ends at the iliac crest, and the lower aspect is outlined by the horizontal gluteal crease.The gluteus maximus has two insertion points: 1â3 superior portion of the linea aspera of the femur, and the superior portion of the iliotibial tractus. Pygalgia is soreness in the buttocks, i.e. a pain in the rump. 2  Steatopygia is a marked accumulation of fat in and around the buttocks. 3  Uropygial in ornithology means situated on or belonging to the uropygium, i.e. the rump of a bird.
