Because the outside of an axon's membrane is not charged and the inside is at -70mV, the membrane of an axon has a potential difference across it. The membrane of an axon is therefore said to be polarised. There is an uneven distribution of ions across the cell membrane of an axon than would be expected from just diffusion occurring.
