Action Potential
Potential, ok well we all know it's a potential, but which one? Is it Action Potential, Synaptic Potential or Membrane Potential. Just saying Potential isn't saying much?
Although there are many polar molecules in a resting neuron the overall charge is zero. Neurons don't actually send electrical pulses in the same way as computers or other electric circuits. The main neural transmitter that carries a charge across the synapse is acetylcholine not individual electrons.
The electrical potential of the cell body changes during an action potential from a negative potential of around -70 mV to a positive potential of +40 mV. The resting potential, however, remains constant.
The resting membrane potential
Action Potential
Is called depolarization.
This is the definition of "resting potential".

Action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, which include neurons, muscle cells, and endocrine cells, as well as in some plant cells. In neurons, they play a central role in cell-to-cell communication.
