Definition
The laryngeal part of the pharynx (Laryngopharynx; Hypopharynx) reaches from the hyoid bone to the lower border of the cricoid cartilage, where it is continuous with the esophagus.
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.
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.
