Everyday Health explains that the gluteal muscles, abductor muscles, iliopsoas muscle and rector femoris muscle attach to the hip bones. These muscles provide range of motion in the hip, keep the body upright and assist with walking.
According to Everyday Health, each muscle is attached to a specific location on the hip and is responsible for a different function. The gluteal muscles attach to the back of the hip to help hold up the body and allow the body to walk. The other muscles attach to the hips and comprise the thighs. Each muscle is responsible for flexion, abduction and movement.
