We have studied the major muscles of the head and neck in this course. Many problems encountered by patients are be related to the muscular system. Of course, the muscles do not exist in a vacuum. They are generally connected to bones and each skeletal muscle fiber relies on a nerve fiber to signal the proper time to contract so the nervous system is an important player also. Therefore, the nerves and attachment points of each muscle are important in the understanding of the skeletal muscles of the head and neck.
