The neuron is essential an information processing and transformation piece of the nervous system. The occurrence of action potential happens when the neuron is “fired up” and moves from a resting state. For example: When you are sleeping and getting rest for work the following day. When neurons are at rest then they are not sending messages electrochemically for your body to react. An inactive neuron or unstimulated one is at rest when it under 70 millivolt and has a negative charge (Carlson, 2013). Then when the alarm goes off for you to “wake up”, that will put you into action potential. This happens when neurons send information down from the axon, going away from the cell body. In this state of action potential the neurons are active and relaying information from cell to cell through axons by way of neuron to neuron. Copyright © 2015 by University of Phoenix.
