arytenoids

Approximation of the arytenoids is a part of the mechanism of closure of the larynx.

The thyroid is first affected, then the cricoid, and the arytenoids much later.

The Child-Voice in Singing treated from a physiological and a practical standpoint and especially adapted to schools and boy choirs Francis E. Howard

Muscles which pass from the cricoid cartilage to the outer angle of the arytenoids act to bring the vocal cords close together, and parallel to one another, so that the space between them is narrowed to a slit.

A Practical Physiology Albert F. Blaisdell

The epiglottis and the two rounded eminences corresponding to the arytenoids must be in the mind's eye, for it is only on deep, relaxed inspiration that anything like a typical picture of the larynx will be seen.

After identification of the epiglottis, too deep insertion of the laryngoscope must be carefully avoided lest the spatula be inserted back of the arytenoids into the hypo-pharynx.

The larynx of a child is very freely movable in the neck during respiration and deglutition, and has a strong tendency to retreat downward during examination, and thus withdraw the epiglottis after the arytenoids have been exposed.

Closure of the larynx is accomplished by the approximation of the ventricular bands, arytenoids and aryepiglottic folds, the latter having a sphincter-like action, and by the raising and tilting of the larynx.

Cicatricial types of postdiphtheritic stenosis may be seen as webs, annular cicatrices of funnel shape, or masses of fibrous tissue causing fixation of the arytenoids as well as encroachment on the glottic lumen.

The _arytenoids_ form the upper posterior boundary of the larynx and our particular interest in them is directed toward their motility, for the rotation of the arytenoids at the cricoarytenoid articulations determines the movements of the cords and the production of voice.

To insert the esophagoscope in the midline, posterior to the arytenoids, requires a degree of force dangerous to exert and almost certain to produce damage to the cricoarytenoid joint or to the pharyngeal wall, or to both.
