Trapezius Muscles (upper back)
shoulders
The spine is bordered by several groups of muscles, including the intertransversarii muscle which facilitate movement between the individual vertabrae, and the multifidus spinae, which facilitate the movement of the spine as a whole. Other muscles in the back are associated with the movement of the neck and shoulders. The trapezius muscle, which is named from its trapezium-like shape, runs between the neck, the anterior chain, the two shoulders, and the thoracic vertebra, T12. The large latissimus dorsi make a triangle from the shoulder to the hip.

Its functions are to move the scapulae and support the arm.The trapezius has three functional regions: the superior region (descending part), which supports the weight of the arm; the intermediate region (transverse part), which retracts the scapulae; and the inferior region (ascending part), which medially rotates and depresses the scapulae.
