Storyboard Text

  • This soup doesn't taste very good. Is there a reason for that?
  • There sure is! Your tongue has receptors which collect information and send it to your brain.
  • Yea! and there is a tongue diagram that tells you where food is sweet, sour, bitter, salty, or umami on your tongue. However, it's wrong. you can taste all of those anywhere on your tongue.
  • Did you know that "Umami" is  Japanese word for savory?
  • Whenever we eat food, chemicals are released in the mouth. Those chemicals reach taste buds which then contact nerve cells. Those nerve cells then work in a chain reaction and transmit messengers to other cells to activate more nerve cells. 
  • How do we taste then?
  • When enough nerve cells are activated, a signal is sent to the brain. Finally, the brain determines what type of taste.
  • Wow that is amazing!
  • You cannot taste well when you have a cold, because channels are blocked and nerve impulses cannot be transmitted to the brain.
  • So then why can't I taste when I have a cold?
  • It sure is! You're welcome!
  • Isn't Anatomy amazing? Thanks for the lesson!
