Description: Animation. Potassium, sodium and chloride are ionic species that occur within and outside living cells. They can diffuse through the cell membrane through specific ionic channels. Differences in the concentrations of the ions between the intra-and extra cellular fluids together with the specific permeability course a voltage difference across the cell membrane (Nernst and Goldman equations). The differences in concentrations inside and outside the cell are maintained by the sodium/potassium pump. It is shown how membrane potential can be measured.
