Keyword: Taste buds
- Most taste buds are on the tongue but some are on the roof of the mouth in the back.
- Your taste buds are connected to your medulla, that is the lower part of the brain. It then travels to the higher part of the brain called the cerebral cortex where you actually receive the taste, then your brain figures it out and tells you. All in a short amount of time.
- Taste buds are actually sensory organs - the little bumps on your tongue are called papillae.(Puh-pill-uh).
- Papillae have microscopic hairs on them called microvilli.
- When you place something in your mouth, the microvilli are the first to get it. Then they send it to the medulla, then the cerebral cortex, then you get the taste.
- An average person has about 10,000 taste buds and when some dull they get replaced approximately every two weeks. But as you age, they don't always get replaced so some elderly people might only have 5,000 so food might taste stronger to a kid than an adult .
Keywords: Does the color of food effect what it tastes like.
- Red - your brain thinks sweet like strawberry.
- Yellow - your brain thinks sour like lime or lemon.
- Bright green - you brain thinks tart like a green apple.
- Black or purple or dark green - your brain thinks rotten or bad.
- Dairy foods are usually pale or white unless they have food coloring in it.
- Vegetables and fruits are usually red, green, yellow or red.
- Meat is usually brown or a darker red and since you have lived for a few years your brain has memorized all of the colors of food; if you eat something new you remember the taste and you can use that knowledge in the future.
- Your brain will also immediately reject any food that looks moldy or stale like green bread and your nose helps with that because if you can't see that milk is bad, if you smell it you will definitely know.
