Transcript of Taste

Taste So, what is taste? I know that it is a sense, but how do you actually taste something? Well, taste is the ability to respond to tastants, which are tiny, dissolved molecules
and ions. The way we detect taste is with tiny cells that are clustered inside of our taste buds. These cells are called taste receptor cells. Taste buds all have openings that allow the food particles to reach the taste receptor cells, giving us the ability to taste things.
("The Sense")
Okay, so now I know that the taste buds and these receptor thingies are the reason I taste things. That's great, but how does my mouth distinguish which taste is which? Actually, the taste receptors in your taste buds send a message to your brain via sensory nerves. Your brain then processes and tells you what flavor you are tasting. ("Taste") Taste buds are made to recognize different flavors. There are four basic types of flavors: salty, sour, sweet, and bitter. The salty and sweet taste buds are at the front of your tongue, the sour buds line the sides of your tongue, and the bitter taste buds are at the back. ("Taste") What about when a person can't taste things? What is that called? The alteration, reduction, or distortation of a person's sense of taste is called dysgeusia. Many things can cause dysgeusia, but the most common reasons are smoking, medications, irritants such as insecticides, and illnesses such as the cold or strep throat. Dysgeusia can be broken down into more detailed problems: hypogleusia (a reduced ability to taste), ageusia (an inability to taste), and parageusia (a constant bad taste in the mouth). ("Sicklick) 50-100 taste receptor cells can be located in one taste bud ("A Sense"). We have about 10,000 taste buds in our mouths ("Taste"). Insects, having the most developed sense of taste, have taste organs on their feet and antennae, as well as their mouthparts. ("Taste") In general, girls have more taste buds than boys ("Taste"). Taste is, out of the five senses, the weakest ("Taste"). JACOB ARIE Slicklick, Andrew M. "Dysgeusia (Taste Disorder), Directory of Dentists, Dental Care and Cosmetic Dentistry."
