The sense of touch is activated by neural receptors such as hair - TopicsExpress



          

The sense of touch is activated by neural receptors such as hair follicles found in the skin, but also pressure receptors on the tongue and throat. The taste of food, is detected by sensory cells called taste buds located on top of the tongue. There are five basic tastes: sweet, bitter, sour, salty and savoury. Smell, like taste, is deemed to be a chemical sense. There are hundreds of olfactory receptors or sensory cells in our nasal passage, each of which will bind itself to a different molecular smell feature. Around 80% of what we think is taste is actually smell. Flavor, is a combination of taste and smell perception. Test this yourself by holding your nose closed the next time you eat something, can you taste it very well? Chances are you cant. #hina
