The epiglottis (pl.: epiglottises or epiglottides) is a leaf-shaped flap in the throat that prevents food and water from entering the trachea and the lungs. It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along ...
The glottis (pl.: glottises or glottides) is the opening between the vocal folds [1] (the rima glottidis). [2] The glottis is crucial in producing sound from the vocal folds. Etymology
Epiglottic vallecula. (Vallecula labeled at center right.) 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 ...
The epiglottis may be active, contacting the pharynx, or passive, being contacted by the aryepiglottal folds. Distinctions made in these laryngeal areas are very difficult to observe and are the subject of ongoing investigation, and several still-unidentified combinations are thought possible. The glottis acts upon itself.
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:
Vocal folds (speaking) In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent ...
Brachyglottis is a genus of flowering plants in the family Asteraceae.The genus was erected on November 29, 1775, [2] [3] by Johann Reinhold Forster and Georg Forster.The name was derived from the Greek brachus ("short") [4] and glottis ("the vocal apparatus of the larynx" [5]) a reference to the size of the ray florets.
Illustration from Floral Poetry and the Language of Flowers (1877). According to Jayne Alcock, grounds and gardens supervisor at the Walled Gardens of Cannington, the renewed Victorian era interest in the language of flowers finds its roots in Ottoman Turkey, specifically the court in Constantinople [1] and an obsession it held with tulips during the first half of the 18th century.
