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.
Scientists describe five basic tastes: bitter, salty, sour, sweet, and umami that the tongue can detect, some people believe that there are areas of the tongue that detect these tastes - (the front tip of the human tongue for salty and sweet, the sides for sour things and the back of the tongue for bitter things). However many scientists now believe that the taste buds over the whole tongue are all involved.
It is important to note that the while the tongue is involve in the taste of things it is actually the scene of smell at the back of the nose that is the best detector for the more complete taste of the foods we eat. You can prove this by holding you nose while eating - food seems to have no taste when you do this.
There is no specific part of the tongue dedicated to any particular taste (sweet, sour, bitter, etc). There are various tastebuds tuned to the specific tastes, however these are scattered randomly across the tongue.
The tip of your tongue.
with the help of tasting buds
Apex or tip of the tongue.
Sweetness was previously believed to reside only at the tip, however newer research shows that taste occurs for all five sensations over the entire surface of the tongue.
== == Simply because the sensory cells have been badly damaged. This happens because of the "desensitization" of sensory receptors on the sensory cells of your tongue. This phenomenon occurs in all of our senses, where a strong and continuous stimulus desensitizes us to the same stimulus, so that it is harder to detect. For example, this is how you adjust to new smells, or why it�s harder to hear after attending a loud concert. It is part of how your body is able to adapt to new environments. There are multiple ways in which the sensory cells of your sensory organs regulate and "desensitize" these receptors. For instance sensory receptors on the cell surface can be deactivated or cells can internalize the receptors and degrade them, both of these events effectively reduce the number of functioning receptors on the cell surface and thus reduces its ability to detect a stimulus.
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)
Sweetness does not depend on the amount of material. It is an intensive property.
These are called receptors. They can be of many different types, depending on what they perceive. Photoreceptors: Pick up light - like your eyes Chemoreceptors: Detect chemicals - like your nose and tongue Haptic receptors: Detect touch - like your skin
Sweetness was previously believed to reside only at the tip, however newer research shows that taste occurs for all five sensations over the entire surface of the tongue.
Yes, the tongue can detect pressure.
The pH of what you are eating or drinking.
The four basic tastes are bitter tastes, sweet/sugary tastes, salty tastes and sour tastesSweet, Salty, Sour and Bitter.
Bitterness, saltiness, sourness, and umami are the five basic tastes that our tounge's detect.
Get the main theme of this essay and conclude your Own summary:The writer tells his experience that how he was shaved by different People... and how they use the techniques of attracting the customer and then sells their stuff... the focus of the writer is on the techniques of different merchants and professionals... their sweetness of tongue... and selling their goods. which actually is not of that price but they use techniques of sweetness of their tongue and sells their items.
Cells on the tongue that detect and respond to different flavors, allowing for the sense of taste.

The tongue's receptors are taste buds. They are specialized to detect flavors, and are divided into two types, sweet and bitter receptors. They can detect perceptions of flavors in five types; salty, sweet, bitter, sour, and umani (savory).
Studies suggest that cats can not detect sweetness. In cases where a cat chooses to eat something sweet, like ice cream, scientists hypothesize that this is because of the temperature ans texture of the ice cream, not the flavor.
The area of the tongue that controls the taste and sensation of bitterness is located primarily in the back of the tongue, close to the uvula and going back towards the throat. The area of the tongue that controls the taste of sourness is located in the lateral-back of the tongue. The area that controls the sensation of saltiness is located on the lateral front of the tongue, and the part of the tongue that controls the sensation of sweetness is on the tip of the tongue.
Papillae are projections on the tongue, add roughness to aid licking and contain taste buds for sensing sweetness, sourness, saltiness and bitterness.
