The buttocks are the two rounded portions of muscle and fat located at the back of the human body, just below the lower back. They play a crucial role in various movements, such as walking, running, and sitting. The primary muscles in this area are the gluteus maximus, gluteus medius, and gluteus minimus, which help support the pelvis and maintain balance. In addition to their functional importance, the buttocks also have aesthetic significance in many cultures. They can vary in size and shape among individuals, influenced by factors such as genetics, diet, and exercise. The appearance of the buttocks is often a focus in fitness and fashion discussions.
