The gluteus maximus (or glutæus maximus) 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. It is a broad and thick fleshy mass of a quadrilateral shape, and forms the prominence of the nates. Its large size is one of the most characteristic features of the muscular system in humans, connected as it is with the power of maintaining the trunk in the erect posture. Other primates have much flatter buttocks. The muscle is remarkably coarse in structure, being made up of fasciculi lying parallel with one another and collected together into large bundles separated by fibrous septa.
NOW, with the anatomy and physiology part of this article out of the way, let’s get right to the butt of things. Let’s start your weekend off right, with a collection of muscular backsides that will keep you smiling through Monday morning!
