superficial back muscles
Muscles originating from the vertebral column and having their fleshy bellies located in the back, but inserting onto the appendicular skeleton of the upper limb or the ribs. They are not innervated by dorsal primary rami of spinal nerves, as are the deep or true muscles of the back; includes the trapezius muscle (innervated by spinal accessory nerve) and latissimus dorsi, rhomboids, levator scapulae, and thoracic muscles (innervated by ventral primary rami of spinal nerves, or derivatives thereof).
