Superior laryngeal vein

Superior laryngeal vein is a vein that drains the larynx and is a tributary of the superior thyroid vein. It is a part of the human circulatory system and plays a crucial role in the drainage of blood from the larynx.

Etymology

The term "superior laryngeal vein" is derived from the Latin words 'superior' meaning 'above', 'laryngeal' referring to the 'larynx' or 'voice box', and 'vein' which is derived from the Latin word 'vena'.

Anatomy

The superior laryngeal vein originates from the larynx and drains into the superior thyroid vein. It is closely associated with the superior laryngeal artery and the internal laryngeal nerve. The vein is located in the neck and is part of the circulatory system that is responsible for the transportation of deoxygenated blood from the body back to the heart.

Function

The primary function of the superior laryngeal vein is to drain deoxygenated blood from the larynx. This is crucial for the overall functioning of the larynx and the circulatory system. The vein works in conjunction with the superior laryngeal artery, which supplies oxygenated blood to the larynx.

Clinical significance

Any damage or blockage to the superior laryngeal vein can lead to serious health complications. These can include laryngeal edema, laryngeal spasm, and other laryngeal disorders. It is also important in surgical procedures involving the larynx or the neck.
