This resting potential is created by a concentration gradient of sodium ions and potassium ions. Since the resting membrane potential of the squid neuron is approximately -65 mV K is the ion that is closest to being in electrochemical equilibrium when the cell is at rest. Explain how action potentials are generated and propagated along neurons.

The resting potential is determined by concentration gradients of ions across the membrane and by membrane permeability to each type of ion. Traditionally the electrical potential difference across a cell membrane is expressed by its value inside the cell relative to the extracellular environment.
