Musculus gluteus medius

The video tutorial covers the anatomy and function of the gluteus medius and minimus muscles, part of the posterior group of dorsal hip muscles. It explains their origins, attachments, and proximity to the piriformis muscle. The tutorial also discusses the nerve connections via the superior gluteus nerve and highlights the muscles' roles as strong abductors of the hip joint, detailing their actions during contraction.
