The value that stays the same as long as there are no signals in the neuron is known as resting potential.
Neurons are the nerve cells. These are the longest cell in the human body. The structure of a neuron comprises of a cell body from which arise the various branch-like extensions called the dendrites. From one end emerges the axon that ends at the axon terminal.
Resting potential is the potential difference of ions across the plasma membrane when the cell is resting and no nerve impulse is being conducted. The value of resting potential is approximately -70 mV in majority of the neurons.
