Superficial back muscles

The video tutorial covers the anatomy, innervation, and actions of superficial back muscles, including the trapezius, levator scapulae, rhomboid, and latissimus dorsi. It explains the difference between superficial and deep back muscles, focusing on their roles in supporting and moving the upper limb and vertebral column. The trapezius muscle is highlighted for its unique fiber orientations and functions, while the levator scapulae and rhomboid muscles are discussed for their roles in scapula movement. The latissimus dorsi is described as a broad muscle involved in humerus movement.
