The sternocleidomastoid muscle has two heads, one originating in the sternum and one in the clavicle; insertion of this muscle is into the mastoid process. When the sternocleidomastoid muscles act together they flex the neck. When one acts on its own it flexes the neck laterally and rotates the head.

These are important muscles to consider if your patient has, for instance, had a whiplash cervical extension/flexion injury and complains of generalised facial and cervical spine pain (Figure 2.17).
