Consider the cell potentials

Webpotential for a neuron is around -70mv. Although all tissues exhibit resting membrane potentials, some respond in a unique and predictable way when they are stimulated. We call these cells excitable. Excitable cells have resting potentials that range from -50mv to -85mv, while non–excitable cells have potentials that range from -5mv to -10mv.
