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. [WP,unvetted]. trapezius The sternomastoid and the three parts of the trapezius are branchiomeric muscles that have secondarily acquired an attachment to the pectoral girdle. They evolved from the fish cucullaris.[well established][VHOG] MA:0002398 UBERON:0002380 superficial back muscle
