|MadSci Network: General Biology|
The cells in the taste buds are renewed. Practically all of the cells in your body are slowly replaced, except your brain cells and your heart cells. Some cells are replaced pretty quickly (like your skin cells and the cells in your intestines), and other cells are replaced more slowly, like those in your bones and liver. The taste bud receptor cells themselves are replaced every 1 to 2 weeks. Below are some places where you can find more information about the sense of taste: http://faculty.washington.edu/chudler/tasty.html http://www.ultranet.com/~jkimball/BiologyPages/T/Taste.html http://www.sciam.com/2001/0301issue/0301smith.html Thanks for your excellent question.
