Posterior pharyngeal walldivided vertically and stitched aside, revealing the naso-pharyngo-laryngo-oesophageal region; lookingforward. CHAPTER XII. Anatomy and Physiology of the Palate and Pharynx. The palate is composed of an anterior (hard) and a pos-terior (soft) portion. The former is bounded anteriorly and lat-erally by the alveolar processes, posteriorly by the soft mucous covering is tightly adherent to the periosteum; ithas a median ridge and lateral corrugations, and is lined withsquamous epithelium; under it are numerous glands. The softpalate (velum pendulum palati) is attached to the posteriorborder of the hard palate,—with which it is continuous,—thelateral walls of the pharynx, the edges of the base of thetongue, and the nasal fossae.
