Neck muscles are bodies of tissue that produce motion in the neck when stimulated. The muscles of the neck run from the base of the skull to the upper back and work together to bend the head and assist in breathing.The motion of the muscles of the neck are divided into four categories: rotation, lateral flexion, flexion, and hyperextension.t is important to keep the muscles of neck strong to maintain proper function and avoid injuries and neck pain. The main function of the muscles of neck is head movement, but they also contribute to the maintenance of blood flow to the brain and holding the head upright.
Working individually, these muscles rotate the head or flex the neck laterally to the left or right. Neck muscles contract to adjust the posture of the head throughout the course of a day and have some of the greatest endurance of any muscles in the body.
