All of it.
The 'tongue map' taught widely in schools, was meant to show which part of the tongue tasted what. According to the map, the tip of the tongue tastes sweet things while at the back tastes bitter things. The sides were for tasting salt and sour. This was based off German research published in 1901 but a person at Harvard University mistranslated it. The original research showed that the areas had relative sensitivity to the 'four basic tastes' while the mistranslated version showed that they could only be tasted in one zone.
the taste buds detect the taste.
i know for sure that each part of the human tongue can taste different things.. like the tip tastes Sweet sides taste sour, and the back taste bitterness. .(parts of the tongue)
The tongue has groups of taste buds in certain areas which are able to detect the different basic tastes.
Taste is detected by sensory receptors (chemoreceptors) in our taste buds, which cover the tongue but are also found in the soft palate of the mouth and the throat. The cranial nerves associated with taste are the glossopharyngeal (VII), facial (IX) and vagus (X) nerves. When the receptors in the taste buds are stimulated by food, impulses are sent along these nerves to the part of the brain where taste is perceived (in the parietal lobe) The area of the tongue which is thought to be most sensitive to sweet tastes is the tip.
The tongue however does taste things that are: bitter, salty, sour and sweet.
The ability to taste spiciness comes from sensors on the tip and edges of the tongue. These sensors detect the presence of capsaicin, the compound responsible for the sensation of heat in spicy foods.
Taste buds probably play the most important part in helping you enjoy the many flavors of food. Your taste buds can recognize four basic kinds of tastes: sweet, salty, sour, and bitter. The salty/sweet taste buds are located near the front of your tongue; the sour taste buds line the sides of your tongue; and the bitter taste buds are found at the very back of your tongue.
Taste occurs over the whole surface of the tongue. Certain areas of the tongue may be more sensitive to one of the five tastes humans can register: sweet, bitter, salt, sour, and savory (like garlic).
There are 3 sides the side is sour the back is sweet and the front is salty or spicy .... 2nd Answer: The newer studies of the tongue with regard to taste have shown that the entire front, top, sides, and back are pretty much equal in what they taste; however, it has been shown that certain parts of the tongue are first to be able to taste certain flavors. But once there is enough concentration of a substance to be able to taste it, all parts of the tongue taste the substance pretty equally.
Taste occurs over the whole surface of the tongue. Certain areas of the tongue may be more sensitive to one of the five tastes humans can register: sweet, bitter, salt, sour, and savory (like garlic).
there is actually no specific sections on the tongue regarding sour, bitter, sweet. These taste buds are scattered throughout your whole tongue. There are no receptors for chile/spicy, these are actually pain receptors. You test this on your own. Place a sour candy on any part of your tongue and you will taste sour.
Tongue maps reveal that the tip of the tongue is the part that is the most sensitive to salty taste. However, recent research argues that tongue maps are not valid and that an individual's taste buds experience taste the same.
