An injury to the trapezius muscle would affect what body part?

Explanation:
The trapezius is a large muscle that runs along the back of the neck and upper spine and helps move and stabilize the shoulder blade while also supporting the head and neck. Because its actions include extending and stabilizing the neck, an injury to this muscle would most directly affect the neck region. The hand, knee, and low back aren’t the primary areas controlled by the trapezius, so they’re not the expected parts affected.
