A sheet of muscles covering the back of the shoulders that aids in shoulder shrugs are called the Trapezius muscles.
The muscle known as the trapezius muscles runs from the base of the neck to the middle of the back, passing through the shoulders. You may move your head, neck, arms, shoulders, and torso with the aid of the trapezius muscle.
Additionally, it supports spinal stability and improves posture. The traps may be impacted by muscle strains, which can hurt and limit movement. Both posture and mobility are controlled by the trapezius muscles.
It enables you to turn and tilt your head in all directions. When you lift your arm or throw a ball, the trapezius muscle controls your scapula (shoulder blade).
