The rima glottidis is the opening between the true vocal cords and the arytenoid cartilages.

It is normally subdivided into two parts, that between the arytenoid cartilages is called the intercartilaginous part (or the intercartilaginous glottis, respiratory glottis, or interarytenoid space), and that between the vocal folds the intermembranous part or glottis vocalis.

It is closed by the lateral cricoarytenoid and arytenoid muscles.
