Larynx

The larynx, commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration.

The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter.

The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation.

It is situated just below where the tract of the pharynx splits into the trachea and the esophagus.

The word larynx (plural larynges) comes from a similar Ancient Greek word (λάρυγξ lárynx).
