The superior thyroid artery arises from the external carotid artery just below the level of the greater cornu of the hyoid bone and ends in the thyroid gland.

Relations
From its origin under the anterior border of the Sternocleidomastoideus it runs upward and forward for a short distance in the carotid triangle, where it is covered by the skin, Platysma, and fascia; it then arches downward beneath the Omohyoideus, Sternohyoideus, and Sternothyreoideus.
To its medial side are the Constrictor pharyngis inferior and the external branch of the superior laryngeal nerve.
Branches
It distributes twigs to the adjacent muscles, and numerous branches to the thyroid gland, anastomosing with its fellow of the opposite side, and with the inferior thyroid arteries.
The branches to the gland are generally two in number;
Besides the arteries distributed to the muscles and to the thyroid gland, the branches of the superior thyroid are:[1]
- Hyoid (infrahyoid) artery
- Sternocleidomastoid artery
- Superior laryngeal artery
- Cricothyroid artery
