Which muscle group includes the quadratus femoris?

The quadratus femoris is part of the lateral rotator group of muscles. This group is responsible for the lateral rotation of the hip joint, contributing to movements that involve turning the leg outward. The quadratus femoris, specifically, is located deep in the hip area and plays a crucial role in stabilizing the hip and assisting with lateral rotation. Its function in conjunction with other lateral rotators helps in activities that require external rotation of the thigh, such as walking or pivoting. Understanding this muscle's role is essential for anyone studying kinesiology, as it highlights the complexity of hip movements and muscle interactions in maintaining stability and facilitating motion.
