The buttocks are two rounded portions of the anatomy, located on the posterior of the pelvis and posterior to the hip joints. The large gluteal muscle makes up a large part of each buttock.

The gluteal muscles are the largest muscles in the human body. The upper part of the buttocks is called the sacrum.

The buttocks are made up of three main components: the gluteus Maximus, gluteus medius, and gluteus minimus. The gluteus maximus is the largest muscle in the body and makes up a large part of each buttock. The gluteus medius and gluteus minimus are smaller muscles located on the sides of the buttocks.

The buttocks provide an important function in aiding locomotion by helping to support the weight of the body when sitting or standing.

On average, women tend to have significantly rounder and larger buttocks in comparison to men. The appearance of the buttocks can be a significant factor in sexual attraction.

The appearance of the buttocks can vary greatly from person to person. Some people may have large, round buttocks, while others may have smaller, flatter ones.

The size and shape of the buttocks can be affected by factors such as genetics, body type, and age. Additionally, how much fat is stored in the area can also contribute to the appearance of the buttocks.
