The epiglottis (also called epiglottis in medical terminology ) is a locking device at the entrance to the larynx in mammals . During the act of swallowing , the epiglottis is pressed passively against the entrance to the larynx and closes it incompletely.

The epiglottis is erected by the thyreoepiglotticus muscle and lowered by the aryepiglotticus muscle.

The epiglottis is supported by the epiglottic cartilage ( cartilago epiglottica ). In contrast to the rest of the larynx skeleton, this cartilage is made up of elastic cartilage. It consists of a stem ( Petiolus epiglotticus ) and a body. The stem is through the ligament thyroepiglotticum with the prominence laryngea of the thyroid cartilage and the hyoepiglotticum ligament with the hyoid connected.

In horses , the stalk bears a wedge cartilage ( processus cuneiformis ) on both sides , which supports the vestibular folds ( plica vestibularis ).

A dysplasia can at Kurzripp-polydactyly syndrome , a hypoplasia in Oro-facial-digital syndrome type 8 happen.
