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
The rima glottidis is the narrowest part of larynx. It is longer (~23 mm) in males than in females (17–18 mm). [1]The rima glottidis is an aperture between the two true vocal cords anteriorly, and the bases and vocal process of the two arytenoid cartilages posteriorly.
Epiglottitis is the inflammation of the epiglottis—the flap at the base of the tongue that prevents food entering the trachea (windpipe). [7] Symptoms are usually rapid in onset and include trouble swallowing which can result in drooling, changes to the voice, fever, and an increased breathing rate.
The term laryngeal is often taken to be synonymous with glottal, but the larynx consists of more than just the glottis (vocal folds): it also includes the epiglottis and aryepiglottic folds. In a broad sense, therefore, laryngeal articulations include the radical consonants, which involve the root of the tongue. The diversity of sounds produced ...
Glottal consonants are consonants using the glottis as their primary articulation. Many phoneticians consider them, or at least the glottal fricative, to be transitional states of the glottis without a point of articulation as other consonants have, while some [who?] do not consider them to be consonants at all. However, glottal consonants ...
Laryngospasm is a primitive protective airway reflex that functions to protect against aspiration.However, it may be detrimental if there is sustained closure of the glottis resulting in blockage of respiration that hinders the free flow of air.
The glottis is defined as the true vocal folds and the space between them. It is composed of an intermembranous portion or anterior glottis, and an intercartilaginous portion or posterior glottis. The border between the anterior and posterior glottises is defined by an imaginary line drawn across the vocal fold at the tip of the vocal process ...
The prognosis is affected by the location of the tumour. For the purposes of staging, the larynx is divided into three anatomical regions: the glottis (true vocal cords, anterior and posterior commissures); the supraglottis (epiglottis, arytenoids and aryepiglottic folds, and false cords); and the subglottis. Most laryngeal cancers originate in ...
