Is epiglottis lined with mucosa

Yes, the epiglottis is lined with mucosa. It is covered by a layer of stratified squamous epithelium on its upper surface, which helps protect it from abrasion as it interacts with food. The lower surface of the epiglottis is covered by respiratory epithelium, which is typical of other parts of the respiratory tract. This mucosal lining plays a role in the function of the epiglottis, aiding in its ability to seal off the airway during swallowing.
