which taste is sensed at the sides of the tongue?
Salty and sweet senses, like sugar, are mostly tasted at the tip of the tongue. Bitter tastes, like coffee, are sensed at the back of the tongue. Sour tastes, like lemon juice, are sensed at the sides of the tongue, at the middle and toward the front. The average person has about 10,000 taste buds. Theyâre replaced about every two weeks. But as you get older, some of those taste cells donât get replaced. Your grandma or grandpa, for example, may only have about 5,000 working taste buds.
