Also to know is, where does the SCM attach? Sternocleidomastoid Attachments It originates on the anterior surface of the manubrium, and the superior border and anterior surface of the medial third of the clavicle. The SCM converges into one point and inserts on the lateral surface of the mastoid process and the nuchal line of the occipital bone.One may also ask, what is the origin and insertion of the sternocleidomastoid? The sternocleidomastoid (SCM) muscle is a voluntary, skeletal muscle located on each side of the neck. The SCM’s origins are the sternum and clavicle and its insertion is the mastoid process behind the ear. The actions of the SCM are to flex and rotate the head. what does the Sternocleidomastoid attach to? The sternocleidomastoid muscle is a two-headed neck muscle, which true to its name bears attachments to the manubrium of sternum (sterno-), the clavicle (-cleido-), and the mastoid process of the temporal bone (-mastoid).How does the Sternocleidomastoid work?The sternocleidomastoid muscle flexes the neck and helps with movement of the head. Also, the muscle works with the scalene muscles in the neck during forced inspiration while breathing (inhaling), and it raises the sternum, the bone at the front of the rib cage. Two nerves serve the sternocleidomastoid muscle.
