Explanations: answer key for all 10 questions

Q1: About how many taste buds does an adult have?
Answer: Several thousand
Estimates range from 2,000 to 8,000.
Q2: What does each taste bud contain?
Answer: Dozens of taste receptor cells
They send signals to the brain.
Q3: About how often are taste receptor cells replaced?
Answer: Every week or two
That helps the tongue heal.
Q4: Which is one of the five basic tastes?
Answer: Umami
Sweet, sour, salty and bitter are the others.
Q5: Who identified umami in 1908?
Answer: Kikunae Ikeda
He studied seaweed broth.
Q6: What are the bumps on the tongue called?
Answer: Papillae
Many hold taste buds.
Q7: Which papillae have no taste buds?
Answer: Filiform
They help grip food.
Q8: Is the old tongue map with separate taste zones correct?
Answer: No, all areas sense all tastes
It came from a mistranslation.
Q9: Why does food taste dull with a blocked nose?
Answer: Much of flavor comes from smell
Taste and smell work together.
Q10: How do taste buds often change with age?
Answer: They become less sensitive
Older adults may add more salt.

Taste Buds Quiz – How Your Tongue Renews Its Taste Cells

An adult has several thousand taste buds, each holding dozens of taste receptor cells. These cells wear out quickly and are replaced every week or two, which is why a burned tongue soon recovers.

Taste buds detect five basic tastes: sweet, sour, salty, bitter and umami. Japanese chemist Kikunae Ikeda identified umami in 1908 while studying seaweed broth.

Most taste buds sit on bumps called papillae, though filiform papillae have none. The old tongue map is a myth, since every area senses every taste, and much of what we call flavor actually comes from smell.
