Larynx

The larynx (plural larynges), or voicebox, is an organ in the neck of mammals involved in protection of the trachea and sound production.

The larynx houses the vocal cords, and is situated just below where the tract of the pharynx splits into the trachea and the esophagus.

During swallowing, the larynx (at the epiglottis and at the glottis) closes to prevent swallowed material from entering the lungs; the larynx is also pulled upwards to assist this process.

Stimulation of the larynx by ingested matter produces a strong cough reflex to protect the lungs.
