~~==Introduction==~~

−

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.~~
