Anatomical terms of muscle

The sternohyoid muscle is a thin, narrow muscle attaching the hyoid bone to the sternum, one of the paired strap muscles of the infrahyoid muscles serving to depress the hyoid bone. 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.


Doubling; accessory slips (Cleidohyoideus); absence.

It sometimes presents, immediately above its origin, a transverse tendinous inscription.
