The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or organelles membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).

Tasa de concentración interior contra la exterior de potasio, sodio, cloruro y otros iones en tejidos difusibles o células. También se les llama potenciales de reposo y transmembránico, se miden registrando las respuestas electrofisiológicas en canales iónicos dependientes de voltaje de (por ej.) células nerviosas, músculares, sanguíneas, así como de membranas artificiales.
