The muscles attached to the arytenoid cartilages control the degree of opening.

A third is to constrict the glottis, but separate the arytenoid cartilages that control one end.

The arytenoid cartilages are held in firm apposition in this voice register also.

The membrane runs between the lateral aspects of the epiglottis and arytenoid cartilages on each side.

In the related aryepiglottal trill, the arytenoid cartilages vibrate.

The rima glottidis is the opening between the true vocal cords and the arytenoid cartilages.

They are attached posteriorly to the arytenoid cartilages, and anteriorly to the thyroid cartilage.

The vocal folds are brought together primarily by the action of the interarytenoid muscles, which pull the arytenoid cartilages together.

Its fibers pass backward and laterally, to be inserted into the base and anterior surface of the arytenoid cartilage.

Their main use is to draw the arytenoid cartilages forward toward the thyroid, and thus relax and shorten the vocal folds.

The aryepiglotticus is a muscle of the larynx running in the aryepiglottic fold from the arytenoid cartilage to the epiglottis.

The vocal folds can be held close together (by adducting the arytenoid cartilages) so that they vibrate (see phonation).

Laryngeal paralysis can be unilateral or bilateral depending upon dysfunction of one or both arytenoid cartilages.

Necessary twang (to bring the lower part of the epiglottis and the arytenoid cartilages closer to each other, resulting in a sharper sound)

The vocal processes of the arytenoid cartilages form a firm framework for the glottis but are made of elastic cartilage at the tip.

Cricoarytenoid muscles are muscles that connect the cricoid cartilage and arytenoid cartilage.

Posteriorly, this vibratory portion is connected to the vocal process of the arytenoid cartilage by the posterior macula flava.

If the vocal cords are completely relaxed, with the arytenoid cartilages apart for maximum airflow, the cords do not vibrate.

Lateral cricoarytenoid muscles adduct and internally rotate the arytenoid cartilages, which can result in adducted vocal folds.

Transverse arytenoid muscle adducts the arytenoid cartilages, resulting in adducted vocal folds.

Oblique arytenoid muscles narrow the laryngeal inlet by constricting the distance between the arytenoid cartilages.

Specifically, the muscle that causes abduction of the arytenoid cartilage, the cricoarytenoideus dorsalis muscle, ceases to function.

By rotating the arytenoid cartilages laterally, these muscles abduct the vocal cords and thereby open the rima glottidis.

Posterior cricoarytenoid muscles abduct and externally rotate the arytenoid cartilages, resulting in abducted vocal folds.

The cricoarytenoid articulation (or joint) is a joint connecting the cricoid cartilage and the arytenoid cartilage.
