When a substance reacts chemically with the receptors of taste buds, the sensation of taste is created.
- People lose their perception of taste as they age. By age 20, half of their taste receptors are gone (on average).
- A snake has no taste buds on its tongue. It uses its tongue to bring smells and tastes into its mouth. Receptors in the pits of the snake’s mouth transmit the information to the brain.
- The catfish has about 100,000 taste buds (the average human has about 10,000 taste buds).
- A human’s taste sense interacts with other senses and factors, including smell, texture, and temperature.
- The five basic tastes are saltiness, sourness, sweetness, bitterness, and umami. The question is, how many tastes can a person really taste?
