Superior Thyroid Vein

The superior thyroid vein.

The Superior Thyroid Vein is a vein in the human anatomy that drains blood from the thyroid gland and the larynx. It is a part of the venous system and plays a crucial role in the circulatory system.

Structure

The superior thyroid vein begins in the substance of the thyroid gland, from tributaries corresponding with the branches of the superior thyroid artery. It receives the superior laryngeal vein, and, running down the trachea, in front of the common carotid artery, ends in the internal jugular vein.

Function

The primary function of the superior thyroid vein is to drain deoxygenated blood from the thyroid gland and the larynx. This blood is then transported to the heart via the internal jugular vein.

Clinical significance

Knowledge of the superior thyroid vein is important in surgeries involving the thyroid gland. Its damage can lead to significant bleeding and complications.
