Answer:
The ability to taste sweet, salty, sour and bitter isn’t sectioned off to different parts of the tongue. The receptors that pick up these tastes are actually distributed all over. We’ve known this for a long time. And yet you probably saw the map in school when you learned about taste. So where did it come from? It is true that the tip and edges of the tongue are particularly sensitive to tastes, as these areas contain many tiny sensory organs called taste buds. It is true that the tip and edges of the tongue are particularly sensitive to tastes, as these areas contain many tiny sensory organs called taste buds. Indeed, results from a number of experiments indicate that all areas of the mouth containing taste buds – including several parts of the tongue, the soft palate (on the roof of your mouth) and the throat – are sensitive to all taste qualities.
You can pick the part of this that you really need.
