What is the entry point into the larynx called?

The entry point into the larynx is referred to as the glottis opening. This area is of significant anatomical importance because it serves as the passageway from the laryngopharynx to the larynx, which is critical for both respiration and phonation. The glottis encompasses the vocal cords and the space between them, allowing airflow to enter the trachea and facilitating sound production as air passes through.

The oropharynx is a region of the pharynx situated behind the oral cavity and is not the entry point into the larynx. The tracheostomy refers to a surgical procedure to create an opening in the trachea, bypassing the larynx entirely and is not related to the natural entry point into the larynx. The pharyngeal inlet, meanwhile, is an opening that allows communication from the nasopharynx to the oropharynx, but it does not denote the entrance to the larynx specifically. Thus, the glottis opening is correctly identified as the critical entry point into the larynx.
