How Can the Tongue Taste Different Flavours?

On our tongue grow numerous lumps that look like little nipples through a magnifier. They are named lingual papillae. On each lingual papilla there grows something that looks like flower buds. They are called taste buds by doctors. The taste buds can tell different flavours. Some of the taste buds are m charge of bitter flavours, some of them respond to sweet flavours , some are sensitive to salty flavours, some are responsive to sour flavours, and so on. When people eat sweet food, the taste buds

in charge of sweet flavours tell the cerebrum that the food is sweet. This is how the tongue tells different flavours.
