The Afferent and Efferent Neurons

inner taste pore, from which a pore=canal leads between the epithelial 

 cells to the surface of the epithelium, terminating in the outer taste pore. 



The gustatory cells have stiff hair-like processes (cilia) extending 

 through the inner pore into the pore canal. The number of gustatory cells 

 in a bud varies ; sometimes there are only two or three ; sometimes they 

 are as numerous as the supporting cells. 



The fibers of the glosso-pharyngeal and lingual nerve form plexuses 

 below the epithelium, and from these two sets of fibers rise, one set ending 

 free, in numerous knobbed branches between the epithelial cells, and the

other set entering the taste buds, at the bottom, usually from two to five 

 for each bud. Inside the bud the fibers divide, multiply, and the branches 

 end (usually with minute knobs) between the gustatory and supporting 

 cells. 



CORPUSCULAR AND SPINDLE ORGANS. 



There are several forms of end organs which may be described as con- 

 nective tissue corpuscles or capsules, containing a core of soft material
