Fact: The Tongue

November 14th 2006 09:30

Your tongue can detect only four basic tastes: sweet, salty, sour, and bitter. The tongue is divided into different taste areas, each containing taste buds that are sensitive to one of these tastes. There are over 10,000 microscopic taste buds on the tongue and these are located on or between tiny projections called papillae. Each taste bud contains a cluster of taste cells. When food is chewed, chemicals dissolve in saliva and go into the pores. The chemicals stimulate taste hairs and these send impulses along nerve fibers to the brain's taste areas where the impulses are interpreted. The life span of a taste bud is only 7-14 days.

You are right katyzzz, every limp in the body connects to the brain, that's why it needs so much blood to supply enough oxygen to stay alive and active.
