What are the major muscles of the neck?

The neck is comprised of several major muscles that play a vital role in supporting and enabling movement of the head. One of the key muscles is the sternocleidomastoid, which runs from the sternum and clavicle to the mastoid bone behind the ear. This muscle allows for rotation and flexion of the neck. Another important muscle is the trapezius, which originates from the base of the skull, the vertebrae, and the shoulder blades. It helps in moving and stabilizing the shoulder blades, as well as extending and laterally flexing the neck. Additionally, the scalene muscles, located on the sides of the neck, assist in tilting the neck and aiding in breathing. Collectively, these major muscles work together to support neck movement and maintain proper posture.
