Backof each posterior lip is one of the fossae of Rosenmiiller; thesecontain both mucous glands and adenoid tissue. At the lowerend of the naso-pharynx is a fold of tissue, composed of mucousmembrane, muscles, and glands, which stretches directly acrossthe posterior pharyngeal wall at this point.

Tespiratory pharynx during deglutition. It moves downwardand inward during phonation and deglutition, shutting off thesuperior from the middle pharynx. Its action is best seen inthose who have cleft palate. The oro-pharynx needs no further consideration. The anterior portion of the laryngo-pharynx opens intothe larynx and the lower into the oesophagus. Anteriorly, it isbounded by the epiglottis and the base of the tongue ; the pyri-form sinuses (Fig. 55) are at the anterior lateral portions, behigthe spaces between the thyroid cartilage and the vestibule ofthe larynx. Between the base of the tongue and the epiglottis 158 DISEASES OF THE NOSE AND THROAT.
