The thyroid gland is supplied by two main arteries that form a dual blood supply. The superior thyroid artery, which comes from the external carotid artery, reaches the upper part of the gland. The inferior thyroid artery arises from the thyrocervical trunk of the subclavian artery and supplies the lower part. Together, these two vessels form an arterial network around the thyroid and ensure robust perfusion. The other arteries listed aren’t direct primary suppliers: the common carotid splits into external and internal, but the thyroid is not fed directly by the common carotid; the external carotid supplies the superior thyroid via its branch, while the internal thoracic artery does not supply the thyroid.
