Injury to the trapezius muscle is most likely to affect which body part?

Explanation:
The trapezius spans from the skull and upper spine to the clavicle and shoulder blade, and it plays a major role in neck posture and shoulder girdle movements. Its fibers help lift and rotate the scapula and also contribute to neck extension and stabilization. When this muscle is injured, neck movement and neck-related posture are most directly affected, leading to stiffness or limited rotation/extension and sometimes headaches from poor neck alignment. The hand, knee, and low back aren’t directly governed by the trapezius, so they’re less likely to be affected by an injury to this muscle.
