It provides insulation to the axons and dendrites during depolarization or action potential.
Resting potential
During an action potential the neuron receives a stimulus causing the cell membrane to become more permeable to sodium than potassium, calling the polarity to change.
They lose potential energy.
The absolute refractory period. This period occurs after the action potential has been initiated and is a result of inactivation of the sodium channels. These sodium channels would normally open up to allow sodium influx into the cell during an action potential. The absolute refractory period occurs during an ongoing action potential and is the period in which a subsequent action potential absolutely cannot be generated.This should not be confused with the relative refractory period which occurs immediately following the absolute refractory period (during membrane hyperpolarization). During this period a subsequent action potential is possible, but more difficult to attain.

Generally, this is when the story begins to 'wrap up' but without coming to an end. No new points should be added, unless in preparation for a sequel, and the problem should start to be resolved. The consequences of the story's main events unfold.
the potential energy of the molecules changes during a reaction.
The potential energy of the molecules change during a reaction.
the Nernst potential of Sodium is +60mV. most action potentials do not reach +60mV at peak depoloarization. http://openwetware.org/images/thumb/a/a6/Action-potential.jpg/300px-Action-potential.jpg.png

Depolarization is the first event in action potential. During depolarization, the sodium gates open and the membrane depolarizes.
