Nerve cells communicate through electrical signals that follow an intricate mechanism. Information flows within a neuron through action potentials and passes between neurons through neurotransmitters. Living cells are polarized, meaning that they are more negative on the inside in relation to the outside of the cell. Therefore,a resting potential is established and a change in the voltage is what triggers the generation of the action potential.The electrochemical gradient, selectively permeable membrane and ion flow, and charge separation across a membrane influence the resting potential. The cell membrane is composed of fatty acids and protein channels (some voltage gated and other selectively permeable) that monitor the diffusion of ions
