On the upper edge of the cricoid cartilage are perched a pair of very singular cartilages, pyramidal in shape, called the arytenoid, which are of great importance in the production of the voice.
When the scarring from subglottic stenosis is limited to the back part of the vocal cords (inter-arytenoid region), it is called posterior glottic stenosis.
Creaky voice also called laryngealisation, pulse phonation or, in singing, vocal fry or glottal fry, 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, and forming a large, irregularly vibrating mass.
The arytenoid consists of two pyramid shaped cartilage that lie at the back of the larynz at the upper edge of the cricoid.
Each arytenoid is movable on the cricoid and is connected with one end of a vocal cord.
The largest represents the thyroid cartilage, the next in size the cricoid, and the two smallest the arytenoid cartilages.
When sound is not being produced, the glottis is open and has a triangular form, due to the spreading apart of the arytenoid cartilages and the attached cords.
When in their natural position the arytenoid cartilages resemble somewhat the mouth of a pitcher, hence their name.
A special set of muscles draws the arytenoid cartilages toward each other, thereby bringing their edges very near and parallel to each other in the passage.
* The Vocal Cords* are formed by two narrow strips of tissue which, connecting with the thyroid cartilage in front and the arytenoid cartilages behind, lie in folds of the mucous membrane.
