 of taste is the tongue. But the soft palate and its arches, the uvula, tonsils, 

 and probably the upper part of the pharynx, are also endowed with taste. 

 These parts, together with the base and posterior parts of the tongue, are 

 supplied with branches of the glosso-pharyngeal nerve, and evidence has

 and in the fauces; 7, tonsils; 8, part of the epiglottis; 9, median glosso-epiglottidean fold

been already adduced that this is the principal nerve of the sense of taste. 

 The anterior parts of the tongue, especially the edges and tip, are innervated 

 by fibers from the lingual branch of the fifth, but which arise in the ganglion 

 of the pars intermedia and are distributed in the chorda tympani, figures 387 

 and 388.
