Gluteus maximus
Gluteus Maximus
The Gluteus Maximus (pronunciation: gloo-tee-uhs mak-suh-muhs) 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.
Etymology
The term "Gluteus Maximus" is derived from the Latin words "glutaeus" (buttock) and "maximus" (greatest). This is a fitting name as it is the largest muscle in the human body.
Function
The Gluteus Maximus is responsible for the movement of the hip and thigh. It performs the actions of extension, external rotation, and adduction of the hip. It also aids in maintaining the upright posture.
