. The anatomy of the domestic animals. Veterinary anatomy. THE TONGUE 391. Trachea Crico-arytenoid- (us dorsalis m uscle A rytenoideus m uscle Anjhnoid carti- lages Vocal cord Aditus laryngis Epiglottis Radix lingwje Anterior pillar of soft palate (cut) the ventral surface of the tip. It varies considerably in thickness. On the dorsum it is very thick and dense; underneath this part there is a dense fibrous cord, which extends medially a distance of five or six inches forward from the vallate papillae. On the sides and ventral surface of the tongue the membrane is much thinner and smooth, and can more readily be dissected off the muscular tissue.' From the lower surface of the free part of the tongue a fold of the mucous membrane passes to the floor of the mouth, forming the frenum linguae. Posteriorly a fold passes on each side from the edge of the dor- sum to join the soft palate, forming the anterior pillars of the latter. A thick central glosso-epiglottic fold (Plica glossoepiglottica) passes from the root to the base of the epiglottis; this en- closes the hyoepiglottic muscle. The mucous membrane presents numerous papillae, which are of four kinds—fili- form, fungiform, vallate, and foliate. The filiform papillae (Papilla? filiformes) are fine, thread-like projections which stud the dorsum and the sides of the tip; they are absent on the root. (}n the anterior part they are so small .as to be scarcely visible, but on the pos- terior part they are much larger and give the surface a distinct pile. .The fungiform papillae (Pajjillae fungiformes) are larger ancl easily seen; they are rounded at the free end, which is sup- ported by a neck. They occur princi- pally on the lateral part of the tongue, but are also found scattered over the dorsum. The vallate papillae (Papillae vallatae) are usually two or three in number. The two constant ones are a quarter of an inch or more (ca. 6 to 7 nun.) in diameter, and are found on the posterior part of the dorsum, one on ea
