Sternocleidomastoid branch of superior thyroid artery

Artery: Sternocleidomastoid branch of superior thyroid artery
Latin ramus sternocleidomastoideus arteriae thyroideae superioris
Gray's subject #144 552

The sternocleidomastoid branch of superior thyroid artery runs downward and lateralward across the sheath of the common carotid artery, and supplies the Sternocleidomastoideus and neighboring muscles and integument; it frequently arises as a separate branch from the external carotid.
