What is the opening of the larynx known as?

The opening of the larynx is referred to as the glottis. This structure serves a crucial role in the respiratory and vocal functions of the larynx. The glottis consists of the space between the vocal cords, which are folds of muscle and tissue that can open and close to control airflow and produce sound. When the vocal cords are apart, the glottis is opened, allowing air to pass into the trachea and lungs, while when they are brought together, the glottis closes, enabling sound production when air is pushed through.

In the context of the other terms provided, fauces pertains to the passageway from the mouth to the pharynx and is unrelated to the laryngeal area. Vocal cords refer specifically to the tissues that form the glottis rather than the space itself. Rima vestibuli describes a different opening in the larynx, between the vestibular folds that are located above the vocal cords. Thus, the glottis is specifically defined as the opening, highlighting its significance in both breathing and phonation.
