Epiglottis

Assoc Prof Craig Hacking and Dr Henry Knipe et al.

The epiglottis is a single midline leaf-shaped fibrocartilaginous structure that forms part of the supraglottic larynx and defines the division of the hypopharynx from the larynx. 

The epiglottis projects posterosuperiorly from its stem-like base, which is attached to the thyroid cartilage. It is also attached to the base of the tongue (via median glossoepiglottic folds) and is attached to the pharynx (via lateral glossoepiglottic folds).

The mucosa lining the epiglottis is supplied by the internal laryngeal nerve, a branch of the superior laryngeal nerve from the vagus nerve (CN X).
