Exempel på hur man kan använda ARYTENOID i en mening

• It is a special kind of phonation in which the arytenoid cartilages in the larynx are drawn together; as a result, the vocal folds are compressed rather tightly, becoming relatively slack and compact.
• Although the whole physiological production of whistle tone is not understood, it is known that when the lateral cricoarytenoid muscles are active but the transverse arytenoid muscles inactive, a triangular opening is seen between the arytenoids, the vocal processes contact each other, but the posterior parts at the apex do not contact each other.
• The rima glottidis is the opening between the two true vocal cords anteriorly, and the two arytenoid cartilages posteriorly.
• The muscle closes the rima glottidis, adducting (approximating) the apices of the vocal process to close the ligamentous part of rima glottidis (in which it is synergystic with the oblique arytenoid muscles and transverse arytenoid muscle).
• The muscle's fibres converge to insert onto (the superior, posterior and (minimally the) anterolateral aspects of) the muscular process of the ipsilateral arytenoid cartilage (its medial belly and lateral belly insert onto the muscular process medially and laterally, respectively).
• Laryngeal paralysis in animals is a condition in which the nerves and muscles that control the movements of one or both arytenoid cartilages of the larynx cease to function, and instead of opening during aspiration and closing during swallowing, the arytenoids remain stationary in a somewhat neutral position.
• The arytenoid cartilages allow for movement of the vocal cords by articulating with the cricoid cartilage.
• Another common finding of laryngomalacia involves the posterior or back part of the larynx, where the arytenoid cartilages or the mucosa/tissue over the arytenoid cartilages can collapse into the airway and cause airway obstruction.
• Continuous electromyography of the arytenoid muscle can provide confidence to surgeons that the recurrent laryngeal nerve is not damaged during neck surgeries, such as thyroidectomy.
• The aryepiglottic muscle or aryepiglotticus muscle, often considered the aryepiglottic part of oblique arytenoid muscle, is an intrinsic muscle of the larynx.
• It is superficial to the transverse arytenoid; the oblique and transverse arytenoids are often considered two parts of a single muscle - the interarytenoid muscle (which is then said to have an oblique part and a transverse part).
• The corniculate cartilages (cartilages of Santorini) are two small conical nodules in the larynx, consisting of elastic cartilage, which articulate with the summits of the arytenoid cartilages and serve to prolong them posteriorly and medially.
• Behind, they are bounded by the apices of the arytenoid cartilages, the corniculate cartilages, and the interarytenoid notch.
• Contact granulomas can be physically identified and diagnosed by observing the presence of proliferative tissue originating from the vocal process of the arytenoid cartilage.
• The cricoarytenoid ligament extends from the lamina of the cricoid cartilage to the medial surface of the base and muscular process of the arytenoid cartilage.
• The series of so-called voice aspirates should now properly be considered to involve the voicing mechanism of murmur, in which the air flow passes through an aperture between the arytenoid cartilages, as opposed to passing between the ligamental vocal bands.
• It is situated deep to the two oblique arytenoids; the oblique and transverse arytenoids are often considered two parts of a single muscle - the interarytenoid (arytenoid) muscle (which is then said to have an oblique part and a transverse part).
• It extends between the lateral margin of the epiglottis, and the apex and fovea triangularis of the ipsilateral arytenoid cartilage.
• As the concave bases of the arytenoid cartilages move on the two convex articular surfaces on the cricoid cartilage (at the cricoarytenoid articulations), the vocal processes are brought closer to each other, which permits the vocal folds to make contact (adduct) and abduct.
• Medical treatments may include surgery such as medialization laryngoplasty; arytenoid adduction; or, fat/collagen injections.
