0 relating to the small cartilages (= two pyramid-shaped parts) and muscles that are connected at the back of the larynx
The vocal folds are first brought together by adducting the arytenoid cartilages.
The vocal processes of the arytenoid cartilages showed changes ranging from mucosal erythema to erosion, involving an area of3-5 mm in diameter.
Moreover, the aryepiglottic folds are stretched between the lowered arytenoids and the epiglottis, as a result of tongue advancement.
Moreover, these more complex valves are not organised as a continuum along a single anatomical structural parameter (such as the opening and closing of the arytenoids).
Posteriorly, this vibratory portion is connected to the vocal process of the arytenoid cartilage by the posterior macula flava.
Specifically, the muscle that causes abduction of the arytenoid cartilage, the cricoarytenoideus dorsalis muscle, ceases to function.
The vocal folds are brought together primarily by the action of the interarytenoid muscles, which pull the arytenoid cartilages together.
It is closed by the lateral cricoarytenoid and arytenoid muscles.
