Here are some things you may not have known
about your tongue.
Taste buds are not visible to the naked eye; the little bumps that can be seen on the tongue are actually papillae, which rest on top of the taste buds. These papillae are believed to help create friction during mastication (chewing) to break down food and also to help move food around in the mouth.
The taste cells in our taste buds live for only about two weeks.
Our taste buds can detect taste in .0015 seconds, which is faster than the blink of an eye.
Like fingerprints, each human tongue has its own unique print.
