epiglottis

 [ep″ĭ-glot´is]
the lidlike cartilaginous structure overhanging the entrance to the larynx. adj., adj epiglot´tic. The muscular action of swallowing closes the opening to the trachea by placing the larynx against the epiglottis. This prevents food and drink from entering the larynx and trachea, directing it instead into the esophagus. (See Plates.)
Epiglottis in a sagittal section of the head and neck. From Dorland's, 2000.

ep·i·glot·tis

(ep'i-glot'is), [TA]
A leaf-shaped plate of elastic fibrocartilage, covered with mucous membrane, at the root of the tongue, which serves as a diverter valve over the superior aperture of the larynx during the act of swallowing; it stands erect when liquids are being swallowed but is passively bent over the aperture by solid foods being swallowed.
[G. epiglōttis, fr. epi, on, + glōttis, the mouth of the windpipe]

epiglottis

A leaf-like cartilaginous structure, down behind the back of the tongue, which act as a kind of lid to cover the entrance to the voice-box (larynx) and prevent food or liquid entering it during the act of swallowing.

epiglottis

a thin flexible structure, made of CARTILAGE, with a leaf-like shape that guards the entrance to the larynx (the glottis) and prevents food material entering the TRACHEA during swallowing, when the larynx is moved upwards under the epiglottis.

Epiglottis

El atrapamiento de la epiglotis se produce cuando el apice y los margenes laterales de la epiglotis quedan envueltos por la mucosa epiglotica ventral y el pliegue aritenoepiglotico [21].
In one scene I had to say epiglotis and 16 takes later I still couldn't get it right."
En el nino, la laringe presenta una ubicacion mas alta, inicia a nivel del cuerpo de la vertebra C1 y en el adulto a nivel del cuerpo de C3, a esto se le suma que en el nino la epiglotis es proporcionalmente mas ancha (Monnier, 2011; Garrido et al., 2007).
Las lesiones bilaterales del hipogloso se asocian con muerte por asfixia, ya que una paralisis completa de la lengua ocasiona retraccion por atonia muscular, lo que implica que la lengua desplace la epiglotis inferiormente y se cierre el adito de la laringe, impidiendo la ventilacion traqueobronquial.
[31] estudiaron 30 animales refiriendo las mismas ubicaciones agrupadas en tres regiones: craneal (base de la lengua, faringe/orofaringe, epiglotis) con 39% de los casos; media (esofago en toda su extension) con 16%; y, caudal (entrada al rumen y rumen) con 45%.
Tambien como consecuencia de la intrusion del condilo de la mandibula, al disminuir el espacio posterior para la superficie de la lengua, esta tendra la tendencia a entrar en glosoptosis y asi se alteraran tanto la articulacion de sonidos (fonemas) como la deglucion, primero porque el espacio inter-incisal al tener la punta de la lengua mas anterior y mas baja impide una buena accion peristaltica y, segundo, como en la parte posterior la lengua trata de proyectarse hacia la luz de la faringe, pero por debajo de la orofaringe, la epiglotis tendra menos espacio para funcionar normalmente.
