On either side of the laryngeal orifice is a recess, termed the sinus piriformis, which is bounded medially by the aryepiglottic fold, laterally by the thyroid cartilage and hyothyroid membrane.    From Wordnik.com.  [XI. Splanchnology. 2c. The Pharynx] Reference

Beyond these is the entrance to the larynx, bounded on either side by the aryepiglottic folds, in each of which are two rounded eminences corresponding to the corniculate and cuneiform cartilages.    From Wordnik.com.  [XII.

In front it presents the triangular entrance of the larynx, the base of which is directed forward and is formed by the epiglottis, while its lateral boundaries are constituted by the aryepiglottic folds.    From Wordnik.com.  [XI. Splanchnology. 2c. The Pharynx] Reference

Closure of the larynx is accomplished by the approximation of the ventricular bands, arytenoids and aryepiglottic folds, the latter having a sphincter-like action, and by the raising and tilting of the larynx.    From Wordnik.com.  [Bronchoscopy and Esophagoscopy A Manual of Peroral Endoscopy and Laryngeal Surgery] Reference

The arytenoid swellings are differentiated into the arytenoid and corniculate cartilages, and the folds joining them to the epiglottis form the aryepiglottic folds in which the cuneiform cartilages are developed as derivatives of the epiglottis.    From Wordnik.com.  [XI.

Of these 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.    From Wordnik.com.  [IX.

With the introduction of the direct laryngoscope it is found that the larynx is funnel shaped, and that the adult cords are situated about 3 cm. below the aryepiglottic folds; the cords also assume their true shelf-like character and take on a pinkish or yellowish tinge, rather than the pearly white seen in the mirror.    From Wordnik.com.  [Bronchoscopy and Esophagoscopy A Manual of Peroral Endoscopy and Laryngeal Surgery] Reference
