The gluteus maximus is the outermost buttock muscle.

Gluteus maximus anatomy. It is connected to the coccyx or tailbone as well as other surrounding bones. The gluteus maximus and medius have been partly removed. It lies superficial to the gluteus minimus and the majority of the gluteus medius as well as the obturators piriformis gemelli and quadratus femoris ie.

The gluteus maximus muscle is the largest of three gluteal muscles other two are gluteus medius muscle and gluteus minimus muscle. The gluteal muscles are also responsible for much of the rotation of the hip that has to accompany walking. It is the largest and most superficial of the three gluteal muscles and makes up a large portion of the shape and appearance of each side of the hips.

The gluteus maximus is the largest of the gluteal muscles. By laying over the gluteus medius and minius muscles it builds the most superficial layer of the dorsal gluteal musculature and thus forms the surface anatomy of the gluteal region. Its thick fleshy mass in a quadrilateral shape forms the prominence of the buttocks.

A third climbing muscle gluteus maximus also assists in abduction as well as in maintaining the knee in extension during weight bearing. It is also the most superficial producing the shape of the buttocks. The gluteus maximus muscle is responsible for movement of the hip and thigh.

Standing up from a sitting position climbing stairs and staying in an erect position are all aided by the gluteus maximus. The word minimus refers to this being the smallest of three gluteal muscles that make up the buttocks the other two are gluteus medius and gluteus maximus. Where does the gluteus minimus muscle attach.

When the right leg is swung forward and. Gluteus minimus attaches between the inferior and anterior gluteal lines referred to commonly as the origin or proximal attachment. The hip external rotators.
