8 Amazing Facts You Didn't Know About Your Tongue
YOUR TONGUE CAN LOOK LIKE A MAP…
Geographic tongue is an unusual condition in which a loss of the tiny papillae that normally cover the tongue’s surface creates irregular raised, red patches on the tongue that can resemble continents or islands on a map. Doctors don’t understand the causes of this bizarre condition, though stress, allergies and eating habits may be responsible. Voigt says, in some cases, those patches “might even grow hair.”It's true most taste buds are on your tongue, but there are also taste cells in the back of your throat, on your epiglottis (that flap of cartilage in the mouth at the back of the tongue), your nose and sinuses, all the way down the throat to the upper part of the esophagus. Infants and young children have even more cells that sense taste in the mucous membranes of their lips and cheeks. All these cells send signals to the brain that are converted into what we perceive as taste.
