It is innervated by the [[ansa cervicalis]]. The muscle arises from the posterior border of the medial end of the [[clavicle]], the [[posterior sternoclavicular ligament]], and the upper and posterior part of the [[manubrium sterni]]. Passing upward and medially, it is inserted by short tendinous fibers into the lower border of the body of the [[hyoid bone]]. ==Variations== Doubling; accessory slips (Cleidohyoideus); absence. It sometimes presents, immediately above its origin, a transverse tendinous inscription. ==Additional images== <gallery> Image:Gray116.png|Posterior surface of sternum.
