The Sense of Taste
By: Reese G

How does the sense of taste work?
The tongue is actually is an organ and it is made up of 16 muscles. The tongue has many purposes such as for talking, tasting and eating. The tongue helps in the process of eating. The tongue can taste four different tastes like salty, sweet, sour and bitter. The tongue has many bumps many people thing those are the taste buds but actually they are called papillae. The taste buds are inside the papillae, there are four types of papillae they are vallate most people have 8 to 12 of them, filiform they are very small but there are many of them on the tongue they do not have any taste buds, fungiform they are located near the tip of the tongue they are mushroom shaped and foliated these can sometimes be seen without a microscope they are horizontal. There are about 200 taste buds in each papilla that have taste buds. In each taste buds there are cells called receptor cells there are 50 to 100 receptor cells in each taste bud. The receptor cells pick up the chemical message and change it to an electrical message then it sends the message to the brain.
