Respuesta :
The upper trapezius causes upward rotation of the scapula and the lower trapezius causes upward rotation of the scapula.
The scapula is stabilized and moved by the trapezius muscle. The upper fibres have the ability to stretch the neck and raise and rotate the scapula upward.
The upper fibres of the trapezius help rotate the scapula (shoulder blade) upward, and the lower trap helps depress the scapula (shoulder blade).
In order to stabilize the shoulder blades during overhead motions, we concentrate on engaging the lower traps.
The trapezius controls posture as well as movement. You can turn and tilt your head in any direction thanks to it.
You can also twist your body, bring your shoulders back, and stand up straight with it. The trapezius muscle regulates your scapula as you lift your arm or toss a ball (shoulder blade).
