What is the origin, insertion, and action of the trapezius

Origin-occipital bone, ligamentum nuchae, and spinous processes of thoracic vertebrae
Insertion-clavicle and scapula(acromion and scapular spine)
Action-depends on active region and state of other muscles; may (1)elevate, retract, depress, or rotate scapula upward, (2)elevate clavicle, or (3)extend neck
