Question
How does the tongue detect the sensation of taste?
Advertisements
Solution
The surface of the tongue is with gustatoreceptors. These receptors are sensitive to the chemicals [sweet, salt, sour, bitter, and umami (savory)] present in the food. They are mostly found at the tip and edges of the tongue, making these areas especially sensitive to taste. Fungiform papillae not only detect taste; they also contain sensory cells for touch and temperature. Each papilla has 3 to 5 taste buds in it.
