Uberon definition : A large superficial muscle that extends longitudinally from the occipital bone to
the lower thoracic vertebrae and laterally to the spine of the scapula (shoulder blade).
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].;
Uberon synonym : trapezius;
Uberon related term : spinotrapezius;
Uberon Homology note : 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];
