TASTE AND SMELL 



120. The mucous membrane of the mouth contains the 

 nerve endings which are affected by taste stimuli. The spe-

 a mass of striped 

 muscular tissue, with 

 fibers running in va-

 the whole organ 

 being covered 

 with mucous mem-

 In some animals, as 

 the dog and cat, they 

 are very prominent
