	Meet your epiglottis!
		The epiglottis is a fairly large piece of cartilage that is covered with mucosa, the same pink tissue that lines the mouth and throat.
		The epiglottis acts as a flap valve, protecting the airway when people swallow.
		It is not at all uncommon to see the epiglottis when you ask a toddler to say, "Aaah." Occasionally, this odd bit of anatomy (a "high" epiglottis) persists into adult life.

	Epiglottitis
		The epiglottis is a flap of tissue that sits at the base of the tongue that keeps food from going into the trachea, or windpipe, during swallowing.
		This may cause the throat structures to push the epiglottis backward.
		With continued inflammation and swelling of the epiglottis, complete blockage of the airway may occur, leading to suffocation and death.

	Epiglottis
		The epiglottis is flap of cartilage located in the throat behind the tongue and in front of the larynx.
		The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs.
		When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs.

		The Epiglottis (cartilago epiglottica) is a thin lamella of fibrocartilage of a yellowish color, shaped like a leaf, and projecting obliquely upward behind the root of the tongue, in front of the entrance to the larynx.
		The anterior or lingual surface is curved forward, and covered on its upper, free part by mucous membrane which is reflected on to the sides and root of the tongue, forming a median and two lateral glossoepiglottic folds; the lateral folds are partly attached to the wall of the pharynx.
		The depressions between the epiglottis and the root of the tongue, on either side of the median fold, are named the valleculæ.

	Epiglottis - Encyclopedia, History, Geography and Biography
		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 fold down the epiglottis, and prevent food that should go into the esophagus and stomach from passing into the trachea (windpipe).
		Epiglottis prolapse is caused when the epiglottis folds down to close off the airway during normal breathing.

	Olympus MIC-D: Brightfield Gallery - Epiglottis Elastic Cartilage
		Composed mostly of elastic cartilage, the epiglottis joins the external ear and the auditory tube of the middle ear in utilizing the structural support and flexibility this type of connective tissue imparts.
		Situated behind the tongue and in front of the voice box or larynx, at rest, the epiglottis is upright and allows air to pass through the larynx into the rest of the respiratory system.
		In the elastic cartilage region of the epiglottis, cartilage-forming cells known as chondrocytes and chondroblasts, lacunae (the housing compartment for the chondrocytes within the matrix), and extracellular elastic fibers, are visible when magnified with a microscope.

	Epiglottitis
		The epiglottis is a normal structure in the larynx.
		The normal function of the epiglottis is as a cover that folds over the voice box during the act of swallowing.
		The epiglottis, therefore, is an important structure which helps to prevent swallowed material from entering into the larynx or tracheal airways.

		The purpose of this study was to assess the utility of ultrasound to image the epiglottis and to determine the range of normal epiglottis diameter for men and women.
		After the epiglottis was visualized in both the sagittal and transverse planes, the AP diameter of the epiglottis at the midpoint in the transverse view was measured and recorded for each subject.
		We hypothesize that in epiglottitis the epiglottis would appear significantly larger than the healthy adult epiglottis, as it was shown on plain-film radiography, but we have not had a case of epiglottitis to confirm this.

	[DYSPHAGIA] vocal fold paralysis and dysphagia
		Sensory input from the epiglottis is by means of the internal branch of the superior laryngeal.
		If movement of the epiglottis is produced passively, and by "passive" one can only mean without any action of its own,it is not logical to assume that the epiglottis would absolutely resist all pressures and related actions of other muscles and ligaments if it were entirely dependent on them.
		As described at the beginning, this is not the case and while the INITIAL movement of the epiglottis (as per Ekberg) is "passive" in that it is brought about by action of the hyoid elevators, its subsequent downward movement depends on contraction of the aryepiglottic and thyroepiglottic muscles bilaterally.

	Dorsal Displacement of the Soft Palate in Horses
		The epiglottis, a relatively rigid structure in the back of the throat, is positioned above the back edge of the soft palate, which is an extension of the hard palate (roof or mouth) and serves to separate the nasal and oral cavities (Figure 1).
		This shift in the position of the epiglottis occurs so that food and saliva are directed into the esophagus and not into the trachea.
		Because many nerves important for the function of the muscles of the soft palate, epiglottis and the wall of the throat course along the guttural pouch, it is believed that inflammation in or around the guttural pouch can cause palate dysfunction, which is a possible contributing factor to the development of DDSP.

	HON Mother & Child Glossary, Bacterial Infections in Childhood: Epiglottitis
		The epiglottis is the flap-like cartilage at the base of the tongue that acts as a valve to protect the larynx (voice box) and trachea (windpipe).
		The epiglottis may become infected, a condition termed Epiglottitis, usually by the common bacterial invaders of the throat and respiratory tree (most prominently Haemophilus influenzae, type B).
		In young children (usually between 2 and 7 years old, in whom these structures are smaller) and occasionally in older children as well as teens and adults, the swelling can become pronounced enough to block the airway entirely, creating a life-threatening situation.

		The function of the epiglottis, the superior cartilage of the larynx, during swallowing is debated and developmental changes in its function unknown.
		Prior to a swallow, the dorsal rim of the larynx was firmly held within the sphincter formed by the palatopharyngeal arch, maintaining a patent airway.
		The movement of the epiglottis during swallowing matures prior to the start of the consumption of solid food, and is implicated in the functional separation of the food pathway and airway.

	SpeechPathology.com: treatment for epiglottic dysmotility
		The epiglottis is a cartilage, not a muscle, and therefore does not have the power to move on its own.
		During swallowing, the epiglottis is moved passively by the force of muscles that are attached to it -pulling the tip posteriorly so that it assumes a horizontal tilt and bending the tip down (the 'downfolding' motion).
		The primary attachments at the tip and sides of the epiglottis are to the hyoid bone while the base of the epiglottis, referred to as the petiolus, attaches to the thyroid cartilage ligament.
