A strain to a neck muscle can include any of a number of either deep or superficial muscles located around the neck. The muscles of the neck are responsible for the following movements including flexion (chin to chest), extension (eyes to ceiling), rotation, and lateral flexion (ear to shoulder). neck strain is a painful and debilitating injury because the pain and associated muscle spasm can inhibit any and all movements of the head/neck. For an athlete who needs to have full movement of his/her head, a neck strain can sideline an athlete until the injury has healed.
