Which muscle is known as the outermost of the three gluteal muscles?

The gluteus maximus is recognized as the outermost of the three gluteal muscles due to its anatomical position and size. It is the largest muscle in the gluteal group, providing structure and support to the hip and pelvis. The gluteus maximus covers both the gluteus medius and gluteus minimus, which are situated underneath it, making it the most superficial layer of the gluteal muscles. This muscle plays a crucial role in maintaining posture, assisting in movement such as climbing stairs, rising from a seated position, and other activities requiring hip extension and external rotation. In contrast, the gluteus medius and gluteus minimus are smaller and located deeper, contributing to stability and abduction of the hip but not being the outermost layer. The rectus femoris is part of the quadriceps group and is not considered a gluteal muscle, which further clarifies the dominance of the gluteus maximus in the gluteal region.
