In the upper trapezius, neck and shoulder we have several small muscles that help us to do different movements and adjustments. Among these muscles feature the rhomboideus minor, the rhomboidesus major, the superior posterior serratus, on the upper trapezius part and the levator scapulae , together with the sternocleidomaistoideus and the semispimalis capitis.

For shoulders, supraspinatus and infraspinatus are generally the most affected.
