The sense of tasting

We taste with our tongue to find out the flavour of food. The sense of smell is also important to taste.

The taste buds contain the receptors for taste.

Taste buds are located in the tongue according to the flavor they can distinguish:

-salty and sweet: near the front.

-sour: at both sides.

-bitter: at the back.

Taste, or gustatory perception, is one of our basic senses. It tells us from early childhood what is edible and what is not, what is good for our body and what can be potentially dangerous. Taking into account how important the sense of taste is for us, it is surprising how little we know about the underlying neurological mechanisms that produce the sensation of taste. 

The food has moleculs that the tonge perceives and informs to the brain about the taste and if it is good or bad.

There are 9 parts:

Epiglottis, lingual tonsils, circumballate popilloe, median sulcus of the tonge, dorsum of the tonge, fungiform popillae, foliate popillae, palatine tonsils and palatopharyngeal arch.

Most of people think that they are 5 tastes, but actually there is a new one, which is umami.
