Tongue and Taste - How it works. - 1 views

  •  The tongue is basically a muscle. This muscle helps the digestive process by doing several things: Move food to the teeth for chewing. Mix saliva into the food. Move food to the back of the mouth for swallowing.

      The tongue is a very strong muscle that helps the digestive process by helping the food mix with the saliva, also for the food to go to the back of the mouth for swallowing, and finally it helps the food go to your teeth for you to chew easily. 
  • As mentioned above, the tongue mixes the food with saliva. As the saliva mixes it is also spreading the solutions and chemicals from the food into the grooves between the papillae on the tongue. The taste buds are located on the papillae and the taste receptors respond to the chemicals from the food. When triggered, the receptors send impulses along the nerves in the tongue up to the brain for processing.

      The tongue helps the food mix with your saliva, but when it starts mixing it sends food chemicals to the cuts on your papillae. The taste buds are in the papillae and the taste receptors respond to the chemicals of the food. When that happens the brain gets signals of how the food tastes like.

  • There's a famous myth that the tongue is the body's strongest muscle. It's not really true -- and not by any definition of strength. But that shouldn't make the tongue any less impressive.

      Everybody says that the tongue is the strongest muscle that you have, but that's not exactly true. But that can't tell you that the tongue is not impressive, because it is. 
  • The tongue is an accessory digestive organ which, along with the cheeks, keeps food between the upper and lower teeth until it's sufficiently masticated, or chewed.

      The tongue is a "accessory digestive organ" that helps food stay between all your teeth until it's entirely chewed.

FYI: Why Does Some Food Taste Bad To Some People And Good To Others? | Popular Science - 1 views

  • ARE YOU A SUPERTASTER? To find out, put blue food coloring on your tongue. Blue dye doesn't stick to taste papillae, so if your tongue doesn't get very blue, you're probably a supertaster. The bluer it gets, the greater the chance you are a subtaster. More hot sauce!

      If you want to find out if you're a super taster, then simply put food coloring on you tongue. Let's say you put blue food coloring on you're tongue. Blue coloring does not stick to your papillae so if your tongue doesn't get very blue, then you're a super taster but if your tongue gets very blue the you're a sub taster.
  • People who have a lot of papillae—the bumps on our tongue, most of which house our taste buds—often find flavors overwhelming. They're "supertasters," and as such they add cream to their coffee and order food mild instead of spicy. Subtasters, on the other hand, have low papillae density and prefer their chicken wings "atomic."

      People who have a lot of papillae normally finds flavors to be a little bit to much, that shows that you're a super taster. But when you're a sub taster you have a very low amount of papillae.  
  • Most toxic plants taste bitter, and nomadic groups that came into contact with a variety of plants would have, over time, developed a variety of receptors. People from malaria-infested parts of the world tend to carry a gene that makes them less sensitive to some bitter compounds, specifically those that contain cyanide.

      People in the past, usually get to the point to eat poisonous food. But how will they know if it's poisonous??? Well once they taste it, they will find the taste very bitter. That would usually tell them that it's toxic.

Taste, Information about Taste - 0 views

  • An individual's unique sense of taste is partially inherited, but factors such as culture and familiarity can help determine why one person's favorite food made be hot and spicy while another just can't get enough chocolate.
    • Isabel Herrera
       
      Taste can also depend on your culture or family traditions and that's why some people love spicy food while other people hate it and prefer chocolate instead.
  • Taste occurs when specific proteins in the food bind to receptors on the taste buds.
    • Isabel Herrera
       
      Taste can happen when the protein in the food your eating joins with the receptors in your taste buds.
  • Taste buds for all four taste groups can be found throughout the mouth, but specific kinds of buds are clustered together in certain areas. Think about licking an ice cream cone; taste buds for sweetness are grouped on the tip of our tongue. The buds for sour tastes are on the sides of the tongue and saltyon the front.
    • Isabel Herrera
       
      The taste buds for all "four taste groups" are usually placed all over the mouth, but taste buds for specific kinds are found in a little group somewhere in the mouth. For example, the taste buds for sweetness can be found in a tiny group in the tip of your tongue. The taste buds for sour are found on the sides.

  • People constantly regenerate new taste buds every 3-10 days to replace the ones worn out by scalding soup, frozen yogurt, and the like. Unfortunately, aspeople grow older, their taste buds lose their fine tuning because they are replaced at a slower rate.
    • Isabel Herrera
       
      A lot of people change taste buds every 3-10 days to avoid the taste buds that had been used for hot soup and frozen yogurt. But as people grow older their taste buds starts losing their ability to taste that's why they're replaced.
  • (The number of taste buds varies in different animal species. For example, cows have 25,000 taste buds, rabbits 17,000, and adult people approximately 10,000.)
    • Isabel Herrera
       
      Different animals have different amount's of taste buds, Fore example cows have 24,000 taste buds, rabbits have 17,000 taste buds and adult people have 10,000 taste buds.
