Question: 2 fuctions of the papillae of tongue.?
Answers:
The top of the tongue is covered with tiny bumps called papillae Papillae give the tongue a rough surface so it can push food around while you chew. Papillae also contain the taste buds, which allow you to distinguish flavors. You were born with about 10,000 taste buds, but they begin to die as you get older; elderly people may have only 5,000.

Each taste bud is made up of cells which contain tiny, sensitive hairs called micro villi; they send messages to the brain, which interprets the signals and identifies the taste. Taste buds can recognize four distinct tastes: sweet, bitter, salty and sour. Some foods can make your taste bud cells less sensitive, especially if they're cold. For example, frozen juice doesn't taste as sweet as the same juice in liquid form.
