Tongue
The tongue is a muscular hydrostat on the floors of the mouths of most vertebrates which manipulates food for mastication. It is the primary organ of taste (gustation), as much of the upper surface of the tongue is covered in papillae and taste buds. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. In humans a secondary function of the tongue is phonetic articulation. The tongue also serves as a natural means of cleaning one's teeth. The ability to perceive different tastes is not localised in different parts of the tongue, as is widely believed. This error arose because of misinterpretation of some 19th-century research (see tongue map).

“All the experts here ... say “There will be no war.” They said the same thing all through July 1914.... In those days I believed the experts. Today I have my tongue in my cheek. This does not mean I am become cynical; but as President I have to be ready just like a Fire Department!”
—Franklin D. Roosevelt (1882–1945)
“As one child psychologist friend of mine explains it with tongue in cheek, your baby only needs a lot of light at night if he’s reading or he’s entertaining guests.”
—Lawrence Kutner (20th century)
