Tasting
For a substance to be tasted, 4 conditions must be met:
1. It must have a taste
2. It must be able to dissolve in saliva
3. It must be in a sufficient concentration to stimulate
receptor cells
4. It must come into contact with the taste receptor
cells

Non Tasting Function
The tongue is used to move food around for chewing
It is composed of muscle fibers that are oriented in
different directions making it very versatile (flexible)
