Sign in to saveThe buttocks (: buttock) are two rounded portions of the exterior anatomy of humans, located on the posterior of the pelvic region. The buttocks are located between the lower back and the perineum. They are composed of a layer of exterior skin and underlying subcutaneous fat superimposed on a left and right gluteus maximus and gluteus medius muscles. The two gluteus maximus muscles are the largest muscles in the human body. They are responsible for movements such as straightening the body into the upright (standing) posture when it is bent at the waist; maintaining the body in the upright post
AI overview
The buttocks are two rounded portions of the exterior anatomy located on the posterior of the pelvic region between the lower back and the perineum, composed of skin, subcutaneous fat, and underlying gluteus maximus and gluteus medius muscles. They are important because the gluteus maximus muscles—the largest muscles in the human body—are responsible for key movements like straightening the body into an upright standing posture and maintaining that upright position.

The buttocks (: buttock) are two rounded portions of the exterior anatomy of humans, located on the posterior of the pelvic region. The buttocks are located between the lower back and the perineum. They are composed of a layer of exterior skin and underlying subcutaneous fat superimposed on a left and right gluteus maximus and gluteus medius muscles. The two gluteus maximus muscles are the largest muscles in the human body. They are responsible for movements such as straightening the body into the upright (standing) posture when it is bent at the waist; maintaining the body in the upright posture by keeping the hip joints extended; and propelling the body forward via further leg (hip) extension when walking or running.
In many cultures, the buttocks play a role in sexual attraction. Many cultures have also used the buttocks as a primary target for corporal punishment, as the buttocks' layer of subcutaneous fat offers protection against injury while still allowing for the infliction of pain.
