( Taste)
Taste (or, more formally, gustation) is a form of direct chemoreception and is one of the five senses. It refers to the ability to detect the flavor of substances such as food and poisons. In humans and many other vertebrate animals the sense of taste partners with the less direct sense of smell, in the brain's perception of flavor. In the West, experts traditionally identified four taste sensations sweet, salty, sour, and bitter. Eastern experts traditionally identified a fifth, called umami (savory). More recently, psychophysicists and neuroscientists have suggested other taste categories (umami and fatty acid taste most prominently, as well as the sensation of metallic and water tastes, although the latter is commonly disregarded due to the phenomenon of taste adaptation.[citation needed]) Taste is a sensory function of the central nervous system. The receptor cells for taste in humans are found on the surface of the tongue, along the soft palate, and in the epithelium of the pharynx and epiglottis. Psychophysicists have long suggested the existence of four taste 'primaries', referred to as the basic tastes sweetness, bitterness, sourness, and saltiness. Umami is now accepted as the fifth basic taste, exemplified by the non-salty sensations evoked by some free amino acids such as monosodium glutamate.[1][2][3] Other possible categories have been suggested, such as a taste exemplified by certain fatty acids such as linoleic acid.[4][5][6] Some researchers still argue against the notion of primaries at all and instead favor a continuum of percepts [7][8][9], similar to color vision. All of these taste sensations arise from all regions of the oral cavity, despite the common misconception of a "taste map" of sensitivity to different tastes thought to correspond to specific areas of the tongue.[10][citation needed] This myth is generally attributed to the mis-translation of a German text, and perpetuated in North American schools since the early twentieth century [11].[citation needed] Very slight regional differences in sensitivity to compounds exist, though these regional differences are subtle and do not conform exactly to the mythical tongue map. Individual taste buds (which contain approximately 100 taste receptor cells), in fact, typically respond to compounds evoking each of the five basic tastes.[citation needed]
