The sternothyroid (sternothyroideus) is a short wide muscle that lies just beneath the sternohyoid muscle. It originates from the first bone of the sternum (breast bone) and from the edge of the cartilage of the first rib and is inserted into the thyroid cartilage. It is innervated by the upper cervical nerves through the ansa cervicalis and is supplied by the inferior and superior thyroid arteries. This muscle acts as a depressor of the thyroid cartilage.
