Unusual Third Head of the Sternocleidomastoid Muscle from the Investing Layer of Cervical Fascia

The abnormal origin, presence of additional head and layered arrangement of fibers are the reported variations of sternocleidomastoid muscle in the past. In the present case we report a rare unusual origin of third head of the sternocleidomastoid muscle in a 60 year-old male cadaver. This additional...
