What is Trapezius muscle?
In [[human]], '''trapezius muscle''' or '''trapezius''' is a large [[muscle]] that extends [[longitudinal]]ly on the upper portion of a [[human]] [[spine]]. Its functions are to move the [[scapula]]e and support the [[arm]].[[File:Trapezius Gray409.PNG|thumb|left|Trapezius muscle shown in red.]] The trapezius has three functional regions: the superior region, which supports the weight of the arm; the intermediate region, which retracts the scapulae; and the inferior region, which rotates and depresses the scapulae. ==Exercising== The upper portion of the trapezius can be developed by elevating the shoulders. Middle [[fiber]]s are developed by pulling shoulder blades together. The lower part can be developed by drawing the shoulder blades downward while keeping the arms almost [[straight]] and stiff. ==Related pages== *[[Bodybuilding]] *[[Strength training]] [[Category:Fitness]] [[Category:Muscles]]
