The tongue has an ingenious design. Receptors responsible for getting information are separate and compartmentalized. So, different areas on the tongue actually have receptors for different types of tastes. This helps us to separate and enjoy the distinct flavors. In this experiment, you will be locating the receptors for sweet, sour, salty, and bitter on the tongue’s surface.

Fascinating! Thanks!
While “spicy” is used to describe how food tastes, it’s not actually a taste. Your tongue can sense heat, cool, and *ouch* (pain), and “spicy” is the combination of hot and *ouch*!
If the tongue only tastes sweet, salty, sour and bitter, then how do we taste something spicy?
