What is the relation of taste and smell in distinguishing flavors ? 



Taste. The surface of the tongue is folded into a number of 

 little projections known as papillae (pd-pil'e). In the folds 

 between these projections, 

 near the root of the tongue, 

 are located the organs of 

 taste. These organs are 

 called taste buds. 



Each taste bud consists 

 of a collection of spindle- 

 shaped neurons, each cell 

 tipped at its outer end 

 with a hairlike projection. 

 These cells send fibers in- 

 ward to other cells, the fibers from which ultimately reach the 

 brain. The sensory cells are surrounded by a number of pro- 

 tecting cells which are arranged in layers about them. Thus
