The video tutorial explains the anatomy and function of the glutei medius and minimus muscles, which are part of the posterior group of dorsal hip muscles. It details their location, origin, and proximity to the piriformis muscle. The tutorial also covers the nerve supply from the sacral plexus and the functional roles of these muscles, including hip abduction, flexion, internal rotation, and stabilization of the pelvis.
