Answer: The cell membrane separates the inside of a cell (all cells, not just neurons) from the outside, and all chemicals that get into and out of the cell must go thorough it. As in all cells, the cell membrane of a neuron is polarized. This means that there is an electrical difference across the cell membrane.
