Epiglottis

From Free net encyclopedia

Template:Infobox Anatomy The epiglottis is a thin, lid-like flap of cartilage tissue covered with a mucous membrane, attached to the root of the tongue, that guards the entrance of the glottis, the opening between the vocal cords. It is normally pointed upward, but when swallowing, solids or liquids stimulate sensors which folds down the epiglottis, and prevents food that should go into the esophagus and stomach from passing into the trachea (windpipe). The epiglottis is one of three large cartilaginous structures that make up the larynx (voice box).

Infection of the Epiglottis

In children, the epiglottis will occasionally become infected with Haemophilus influenzae, Staphylococcus aureus, or Streptococcus pneumoniae bacteria. Although easily treated, this condition is a medical emergency because without treatment the epiglottis may swell and block the trachea, causing asphyxia and death. This condition has become rare in countries where vaccination against Hemophilus influenzae (HIB) is routine.
