This embraces the base of the epiglottis, and, except while swallowing food, shuts off all communication between the cavity of the mouth and the pharynx, respiration being, under ordinary circumstances, exclusively through the nostrils.
Again, from different points of the cortex the assunIption of the requisite positions of the tongue, lips, cheeks, palate and epiglottis, as components in the act of sucking, can be provoked singly.
Epiglottitis is an infection and inflammation of the epiglottis.
Because epiglottitis involves swelling and infection of tissues, which are all located at or above the level of the epiglottis, it is sometimes referred to as supraglottitis (supra meaning above).
Because the epiglottis may swell considerably, there is a danger that the airway will be blocked off by the very structure designed to protect it.
