Taste

Taste

The tongue's surface is covered with tiny, different sized bumps, known as papillae. There are approximately 10,000 of these papillae, which are made up of taste buds. Taste buds contain the specialized receptor cells which allow us to distinguish the different tastes that we know. There are four different taste-sensitive areas on the surface of the tongue: sour, salt, bitter and sweet. [CG] {NR}
