Which muscles cover the back of the neck and upper and middle regions of the back?

The trapezius and latissimus dorsi muscles play significant roles in the structure and movement of the back. The trapezius, a large triangular muscle, spans the upper back and is responsible for moving, rotating, and stabilizing the shoulder blade, while also helping to extend the neck. It covers the back of the neck and extends down to the middle of the back, making it essential in maintaining proper posture and facilitating various upper body movements.

The latissimus dorsi, often referred to as the "lats," covers the lower and middle parts of the back. It contributes to the movement of the shoulder joint and plays a vital role in actions such as pulling and lifting. Together, these two muscles form a significant part of the musculature in the back, allowing for coordinated movement and stability in that region.

In contrast, the other choices do not encompass the specified areas of the back as accurately as the trapezius and latissimus dorsi. The serratus anterior is primarily located on the side of the chest and is involved in the movement of the scapula. The deltoid and pectoralis major are muscles located in the shoulder and chest areas, respectively, and do not cover the back. The rhombo
