The interactions with the taste receptor cells will produce an action potential that will induce an action potential in taste sensory neurons. A neuron has 3 main parts: the dendrite, the cell body, and the axon. Information will be able to move faster in bigger and myelinated axons. In sensory neurons, the action potential is trigger at the dendrite. Each neuron has a cell membrane that encloses each neuron. The cell membrane is semi-permeable which mean certain things can go in and out of it. Since there is a difference in ions concentrations of the extracellular fluid and intercellular fluid, there is a charge of about -70 millivolts inside of the neuron relatively to the outside. This charge is the resting potential charge. So when a taste sensory neurons interacts with the chemicals in the saliva, it triggers an action potential. An action potential occurs when sodium channels in the cell membrane opens up and let Na+ ions to flow into the neuron, causing the inside to become more positive than the outside of the neuron. This process is called
