Epiglottis and Vocal Cords

The epiglottis and vocal cords. Labels: e, the vocal cords; d, the epiglottis.

The epiglottis is a cartilaginous lid for the larynx. It is leaf-shaped, situated behind the base of the tongue, and attached by its apex to the posterior surface of the thyroid cartilage, just below the median notch.
