Transcript of TASTE

Taste
In this presentation you will learn about.....


You guessed it. Taste. Taste is such and awesome sense and I encourage you to start learning about it as well. Just to clarify taste has the least amount of information on it, of the five senses. Now that we've got the intro out of the way, lets get started with the presentation.
TASTE BUD
Now what exactly is a taste bud? Well, a taste bud is what helps you taste. But how does your tongue determine what you are tasting? That's where the taste "qualities" come in. There are five of these qualities. Salty,sour, sweet, bitter, and umami. Now you may be saying to yourself, " What in the world is umami?!" or, if you know what umami means, then you would be saying to yourself, "umami means..."
SALIVA
All over your mouth you have salivary glands. When you see or smell food they produce saliva [spit]. This is called salivating. When chewing, certain proteins in your saliva go to work on the bits of food you chewed up, breaking them down into their component chemicals. The saliva seeps back down to your taste buds, carrying with it the dissolved chemicals from the food. Electrical signals from receptor cells travel along nerves to taste areas in your brain.Some/most signals go to the brain’s cortex. There they become info about what you are tasting.
AGEUSIA
Ageusia is the loss of the sense of taste. This diagnosis is often confused with anosmia which is the loss of smell. Ageusia is the worst of the three taste illnesses I will be talking about. So I already have illness one done which is ageusia. Another taste illness is hypogeusia, which is very similar to ageusia because it is a PARTIAL loss of taste. The third illness is dysgeusia which is a distortion of the sense of taste.
THE END
Just because the title of this slide is the end, it generally doesn't mean it's "the end". Never mind, it does. But before I leave I want to tell you why I didn't put the last few words of my word search in my presentation. So the rest of the words in my word search were excluded from this presentation because... they were words that I guarantee, that you have already heard of. Food {gotta love it}, smell, cook, and food-critic are words that I hope you know. Okay, maybe not food-critic, but it says it all in the name. Food-critic: someone who critiques food. But again thank you for listening and I hope you learned something.
PAPILLAE
Papillae are those little bumps on your tongue. Inside of your papillae is your taste buds. Now when you first came in to this room you probably thought that the little bumps on your tongue were your taste buds. But now, hopefully not. There are four types of papillae; vallate, filiform, fungiform, and foliated. These four types of papillae are all located on different spots on the tongue. Now while I was reading this, have any of you found the next word[s] on your list?
CORTEX
The cortex is responsible for where taste is processed. It is the part or portion of the brain where taste is processed. But it's not this one part that processes it, it's the parts within the cortex that have this responsibility.The cortex is located towards the top part of the brain. Also known as the cerebrum, the cerebral cortex is broken up into two, so called hemispheres. These hemispheres have a total of four lobes- the frontal, parietal, temporal, and occipital lobes. Now that you've got a little background knowledge about the cerebral cortex, let's talk more about the primary gustatory cortex. The primary gustatory cortex is located near the face area of the somatosensory of the parietal lobe, which is located within the insular and opercular cortex of the frontal lobe.

UMAMI
Well, all you fellow people saying, "What in the world does umami mean", here's the answer to you question: Umami is like a meaty or savory flavor. Umami tasting foods also tend to have a lot of L- glumate.
