More Information about the Sternocleidomastoid Muscle
The sternocleiodmastoid muscle is
commonly abbreviated as SCM. In addition to its movement functions, this
paired muscle aids in inspiration along with the scalene muscles.
The sternocleidomastoid muscle is named so because of its anatomy. Since
it originates at the manubrium of the sternum (sterno) & the clavicle (cleido)
and inserts at the mastoid process (mastoid).
