Moreover, just in front of it there is a fold of mucous membrane called the epiglottis, which is in reality a tiny trapdoor closing over the opening when necessity requires.
The epiglottis, which is located at the back of the throat, is a thin, elastic piece of cartilage that covers the trachea during swallowing.
The epiglottis is a small leaf shaped membrane situated immediately behind the root of the tongue and covers the larynx during swallowing.
In betwixt the two openings comes the so-called epiglottis, an organ capable of being drawn over and covering the orifice of the windpipe communicating with the mouth; the end of the tongue is attached to the epiglottis.
This is the epiglottis, which is much like a box lid that swings over the opening between the throat and the voice box.
Symington found that in infants between six and twelve months of age the tip of the epiglottis was a little above the level of the fibrocartilage between the odontoid process and body of the axis, and that between infancy and adult life the larynx descends for a distance equal to two vertebral bodies and two intervertebral fibrocartilages.
In front of the epiglottis are the median and lateral glosso-epiglottic folds passing forwards to the base of the tongue, and enclosing the two valleculæ.
Extending backwards and downwards from the lateral margins of the epiglottis are the two ary-epiglottic folds which reach the arytenoid cartilages posteriorly.
The epiglottis is the valve which closes over the upper opening of the larynx.
Then a flap of tissue called the epiglottis momentarily covers the air pathway and prevents water or food from entering.
