The [[Epiglottis|epiglottis]] is the rostral margin of the larynx.

The epiglottis is a flap of [[Bones and Cartilage - Anatomy & Physiology#Elastic Cartilage|elastic cartilage]] covered by mucous membrane. It forms the rostral boundary of the [[Larynx - Anatomy & Physiology|larynx]] and prevents food particles from entering the trachea.
The epiglottis can return to its normal size and shape after distortion due to the vast amount of elastic fibres present within.

==Histology==
*Covered by mucous membrane
*Irregular elastic fibres
**Dense network of branching fibres around the chondrocytes
**Less dense branching fibres towards the perichondrium
==Species Differences==
===Avian===
*No epiglottis
