This little appendage is covered with mucous mem-brane, and is composed of connective tissue, glands, and theposterior extremities of the two azygos uvulae muscles, which Hard palate Posterior half-archAnterior half-arch Tongue Fig. 56.—The Normal Palate and Pharynx. lie side by side in the median line of the soft palate. Theirfunctions are to elevate the uvula and aid the palato-pharyngeimuscles in separating the mouth and pharynx. The uvulaseems to aid in swallowing, in tone production, and in directingthe post-nasal glandular secretions to the lingual tonsil. In addition to the muscles considered, namely, the palato-glossi, palato-pharyngei, and azygos uvulae, there are two otherpairs of palatine muscles,—the levator palati, which serve toraise the soft palate, and the tensor palati, the action of whichis indicated. These various muscles aid both in deglutition andin vocalization, while the levator palati have another function,—. ANATOMY AND PHYSIOLOGY OF PALATE AND PHARYNX. 153 that of aiding in opening the mouths of the Eustachian tubes,thus permitting aeration of the middle ears. Therefore, thesemuscles have much for which to be accountable, as they areinstrumental in many cases of deafness. The faucial tonsils, or amygdala?, are oval glands, thesize and shape of a hazel-nut. In health they should rarely beseen, unless the anterior pillar be pushed aside; yet they varymuch in size, form, and color within normal limits. Each glandis imbedded in the faucial, peritonsillar tissue, and inclosed ina capsule of connective tissue. On the free surface are fromeight to eighteen openings, the entrances to the crypts (ton-sillar lacunae, or follicular glands). In addition to these, thetonsils contain single-layer cavities, each of which includesseveral follicular folds and procures their common discharge atthe periphery. The crypts of larges
