What does the word pharynx mean?
A species of musculo-membranous, symmetrical canal, on the median line, irregularly funnel-shaped, and situate between the base of the cranium and the oesophagus, in front of the vertebral column. It is very narrow above; but dilates in the middle, and again contracts below, at its junction with the oesophagus. Into the anterior paries of the pharynx open, successively, from above to below, -the posterior orifices of the nasal fossae; the Eustachian tubes; the posterior aperture of the mouth, and the top of the larynx. The pharynx is formed, externally, of a muscular coat, and, internally, of a mucous membrane, which is continuous, above, with the Schneiderian membrane; and in the middle, with that of the mouth below, with that of the oesophagus; and, at the sides, with that of the Eustachian tubes. This membrane has no villi, and presents only a few inequalities, which are owing to the presence of muciparous follicles. The muscular coat of the pharynx is composed of the constrictor muscles, stylopharyngei, and pharyngostaphylini. The vessels and nerves are called pharyngeal. The pharynx serves as a common origin for the digestive and respiratory passages. It gives passage to the air, during respiration; and to the food at the time of deglutition.
