What is the epiglottis?

The epiglottis is the epiglottis, ie the upper part of the larynx. It has a cartilaginous skeleton and is covered with the same mucous membrane as the vocal cords inside the larynx and the mouth. The epiglottis lies above the trachea and closes it during swallowing.

What is the function of the epiglottis?

The elastic epiglottis is passively also pressed upwards against the tongue root, under the tongue, during the swallowing process by the upwardly raised larynx. This closes the entrance to the trachea so that no food particles can get in. Only when trying to speak and swallow at the same time is one "swallowed" because the epiglottis did not completely cover the trachea.

The epiglottis is covered by the same mucous membrane as occurs in the mouth and on the vocal folds. Sporadic buds may appear in the epithelium of this mucous membrane as on the tongue. On the back of the epiglottis, in the dimple of the cartilage surface and in the pocket folds, there are numerous glands, the secretions of which are supposed to keep the mucous membrane moist when speaking.

Where is the epiglottis?

The epiglottis is the upper part of the larynx located in the middle cervical region between the pharynx and the trachea. It lies approximately at the height of the fourth cervical vertebra. In infants, however, it is positioned higher and slips deeper in the course of growing up.

What problems can the epiglottis cause?

An acute inflammation of the epiglottis by bacteria is called epiglottitis. In most cases, Haemophilus influenzae type B bacteria are responsible for the epiglottis. The disease is particularly prevalent in preschool children. The swelling of the epiglottis can lead to shortness of breath and thus to an acute life-threatening situation.

Congenital malformations of the epiglottis may impede inhalation in affected infants.

Around epiglottis can form benign and malignant tumors.
