Superior Thyroid Artery

The superior thyroid artery is an oxygen-rich blood vessel that originates from the external carotid artery. From its point of origin, it descends to the anterior surface of the thyroid gland, giving off the superior laryngeal artery and other smaller branches to the hyoid bone and sometimes to the externocleidomastoid muscle. The superior thyroid artery supplies the thyroid gland, the larynx, hyoid bone, and muscles of the neck.
