The larynx, commonly known as the voice box, is located in the neck and plays a crucial role in breathing, producing sound, and protecting the airway during swallowing. It is composed of several cartilages, including the thyroid cartilage, cricoid cartilage, and arytenoid cartilages, which provide structure and support. The larynx also contains the vocal cords, which vibrate to produce sound when air passes through them. The larynx is situated above the trachea and below the pharynx. It is lined with a mucous membrane that helps keep it moist and protects it from irritants. The epiglottis, a flap of cartilage, covers the larynx during swallowing to prevent food and liquids from entering the airway.
