Here we can see the S.C.M. at work . In it's not abbreviated form it goes by the name of Sternocleidomastoid. Though it is such a long word, it is quite helpful if you are stuck in an anatomy trivia jam, because it tells you all of the attachments!
The S.C.M pushes the head left to right. Being a long muscle that spans from clavicle to just below the ear, when it becomes chronically tight it can contribute to migraines and headaches as it pinches the nerves around it that go up into the sinus cavity. When the S.C.M. becomes fatigued the muscle does not re-condition as quickly in the natural way it does normally. So when having to look further then the side mirrors can take you, this action can be painful or simply unable to comply to the range.
