Final answer:
The superior laryngeal artery, a branch of the external carotid artery, supplies blood to the supraglottic region of the larynx.
Step-by-step explanation:
The artery that supplies blood to the supraglottic region of the larynx is the superior laryngeal artery. This artery is a branch of the external carotid artery, which arises from the common carotid artery. The external carotid artery supplies blood to various structures within the face, lower jaw, neck, esophagus, and larynx, including the supraglottic area. The inferior laryngeal artery, on the other hand, is typically considered to be the terminal branch of the inferior thyroid artery, which arises from the thyrocervical artery (a branch of the subclavian artery), and it supplies the infraglottic region of the larynx.
