aryepiglottic fold

The superior border is in the aryepiglottic fold.

They are strongly pharyngealized, and for some speakers involve low-frequency trilling that presumably involves the aryepiglottic fold.

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

Aryepiglottic fold, at the entrance of the larynx, is a triangular opening, narrow in front, wide behind, and sloping obliquely downward and backward.

A considerable number of the fibers of the Thyreoarytenoideus are prolonged into the aryepiglottic fold, where some of them become lost, while others are continued to the margin of the epiglottis.

Pyriform sinus, extending from the pharyngoepiglottic fold to the upper end of the esophagus, bounded laterally by the thyroid cartilage and medially by the surface of the aryepiglottic fold and the arytenoid and cricoid cartilages.

Of these (sensory) branches some are distributed to the epiglottis, the base of the tongue, and the epiglottic glands; others pass backward, in the aryepiglottic fold, to supply the mucous membrane surrounding the entrance of the larynx, and that lining the cavity of the larynx as low down as the vocal folds.

The cuneiform cartilages of the larynx (cartilages of Wrisberg) are two small, elongated pieces of yellow elastic cartilage, placed one on either side, in the aryepiglottic fold, where they give rise to small whitish elevations on the surface of the mucous membrane, just in front of the arytenoid cartilages.
