Gluteus maximus muscle

Gluteus Maximus Muscle

The Gluteus Maximus Muscle is the largest and most superficial of the three gluteal muscles. It makes up a large portion of the shape and appearance of the buttocks. Its thick fleshy mass, in a quadrilateral shape, forms the prominence of the buttocks.

Anatomy

The Gluteus Maximus Muscle originates from the posterior gluteal line of the inner upper ilium, and parts of the sacrum and coccyx. It extends to the gluteal tuberosity of the femur and the iliotibial tract, a band of strong fibrous tissue that runs along the outside of the thigh.

Function

The primary functions of the Gluteus Maximus Muscle are to extend and laterally rotate the hip, and extend the trunk. It is involved in various actions, including walking, running, and climbing. It is also responsible for maintaining the body in the erect posture.

Clinical Significance

Injury or strain to the Gluteus Maximus Muscle can result in pain in the buttocks, hips, and lower back. Conditions such as sciatica and piriformis syndrome can also affect this muscle.
