This is my video about the muscles of the back. Back muscles anatomy here include the Trapezius, Latissimus Dorsi, Rhomboid and Levator Scapulae... There are other structures in this video like humerus, vertebrae and humerus. Latissimus dorsi anatomy and the Trapezius anatomy is what I expalin in great details. Rhomboids anatomy and Levator Scapulae anatomy is superficially explained.
