A resting nonsignaling neuron has a voltage across its membrane called the resting membrane potential or simply the resting potential The resting potential is determined by concentration gradients of ions across the membrane and by membrane permeability to each type of ion In a resting neuron there are concentration gradients across the membrane for Na and K Ions move down their gradients via    See Answer
