Some larger muscles are labeled. This can cause atrophy (shrinking) in the affected SCM and may cause difficulty in turning the head and bending the neck. Many actions in the body do have one muscle that is responsible for more of the work in that action than any other muscle. The fibers from the accessory nerve nucleus travel upward to enter the cranium via the foramen magnum.
