Laryngoscopy (/ ˌ l ær ɪ ŋ ˈ ɡ ɒ s k ə p i /) is endoscopy of the larynx, a part of the throat. It is a medical procedure that is used to obtain a view, for example, of the vocal folds and the glottis .
The epiglottis is made of elastic cartilage covered with a mucous membrane, attached to the entrance of the larynx. It projects upwards and backwards behind the tongue and the hyoid bone. The epiglottis may be inflamed in a condition called epiglottitis, which is most commonly due to the vaccine-preventable bacterium Haemophilus influenzae.
straight mirror for indirect laryngoscopy (seeing the larynx); structure seen are the base of tongue, vallecula, glossoepiglottic fold, epiglottis, pharyngo-epiglottic folds, aryepiglottic folds, epiglottis, interarytenoid region, pyriform sinus, inlet of larynx, supraglottic region, ventricular bands, vocal cord, subglottis and few rings of ...
The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis. Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold. The valleculae can collect saliva to prevent initiation of the swallowing reflex.
In front, they are bounded by the epiglottis. Behind, they are bounded by the apices of the arytenoid cartilages , the corniculate cartilages , and the interarytenoid notch. [ 2 ] Within the posterior part of each aryepiglottic fold exists a cuneiform cartilage which forms a whitish prominence, the cuneiform tubercle.
It is clinically important in performing direct laryngoscopy with a Macintosh laryngoscope blade; the blade tip is placed in the vallecula and moved anteriorly, which causes the hyoepiglottic ligament to pull the epiglottis anteriorly as well and thus expose the glottis. [citation needed]

Epiglottis: A large, spoon-shaped piece of elastic cartilage. During swallowing, the pharynx and larynx rise. Elevation of the pharynx widens it to receive food and drink; elevation of the larynx causes the epiglottis to move down and form a lid over the glottis, closing it off. Paired cartilages:
