Taste Buds are sensory organs that are found on the tongue. They pick up different tastes. Taste Buds contain taste receptors. Most of the Taste Buds that sense salty or sweet tastes are near the front of the tongue. The Taste Buds for sour tastes are along the sides of the tongue. The ones for bitter tastes are at the back of the tongue. An average person has about 10,000 Taste Buds. Taste Buds are replaced every 2 weeks. A popular myth assigns these different tastes to different regions of the tongue. In reality, these tastes can be detected by any area of the tongue. Via small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with the taste receptors.
