Question

The figure shows a neuron, which is the type of cell your nerves are made of. Neurons serve to transmit sensory information to the brain, and commands from the brain to the muscles. All this data is transmitted electrically, but even when the cell is resting and not transmitting any information, there is a layer of negative electrical charge on the inside of the cell membrane, and a layer of positive charge just outside it. This charge is in the form of various ions dissolved in the interior and exterior fluids. Why would the negative charge remain plastered against the inside surface of the membrane, and likewise why doesn't the positive charge wander away from the outside surface?

Explanation / Answer

Negative charge remains plastered to inside surface and positive charge to outside surface because opposite charges attract each other . Negative and positive charges attract each other but they cannot combine due to presence of membrane which separates positive and negative charge
