|
trapezius |
Origin fixed: adduct scapula, performedchiefly by middle fibers with stabilization by upper and lower fibers. Upward rotation of scapula, performed chieflyby lower fibers, with stabilization by middle fibers. Upper fibers elevate the scapula. Lower fibers depress the scapula.Insertion fixed & actingunilaterally: Upper fibers extend, laterally flex, androtate head and joints of cervical vertebrae so face turns to opposite sideActing bilaterally: upper trapezius extends neckAccessorymuscle to respiration. (Kendall FP)Uppertrap elevates and retracts the clavicle. It’s role as an upward rotator of thescapula is questionable but it is still important to balance the forces during scapularupward rotation. Upper trap is primarilya scapular elevator and retractor. (Ludewig PM)Lowertrap is primarily an external rotator and upward rotator of the scapula. It’s bestas an upward rotator in early range of arm elevation. Lower trap can help withposterior tilt.(Ludewig PM)Middletrapezius externally rotates scapula. It contributes some to upward rotation.(Ludewig PM) |
