While the superior and middle thyroid veins serve as direct tributaries to the internal jugular vein, the inferior thyroid veins drain directly to the brachiocephalic veins. They form a plexus in front of the trachea, behind the Sternothyreoidei. From this plexus, a left vein descends and joins the left brachiocephalic vein, and a right vein passes obliquely downward and to the right across the brachiocephalic artery to
Off-the-Neck Historic District the principal state road leading northward from the village of Castine, which is located at the end of a large peninsula defined by Penobscot Bay on the west and the Bagaduce River on the east.
