What is the largest muscle in the human body?



Gluteus Maximus




Answer: There are about 640 muscles in the body. They come in all shapes and sizes and perform many different functions. The largest muscle in the human body is the gluteus maximus, or the buttock muscles, also known as “the glutes.” These muscles (there is one on each side) help move the hips and thighs, and keep the trunk of the body upright. Furthermore it supports the stabilization of the hip joint. They are the chief muscles that work against gravity when you’re walking up stairs, according to the Library of Congress.



The gluteus maximus (also known collectively with the gluteus medius and minimus, as the gluteal muscles, and sometimes referred to informally as the “glutes”) is the main extensor muscle of the hip. 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. Its thick fleshy mass, in a quadrilateral shape, forms the prominence of the buttocks.



Its large size is one of the most characteristic features of the muscular system in humans,[1] connected as it is with the power of maintaining the trunk in the erect posture. Other primates have much flatter hips and can not sustain standing erectly.

The muscle is remarkably coarse in function and structure, being made up of muscle fascicles lying parallel with one another, and collected together into larger bundles separated by fibrous septa.
