Neuronal Membrane Fluid Separation
The neuronal membrane serves a critical role in keeping a neuron's intracellular fluid (cytoplasm) separate from the surrounding extracellular fluid. This separation is essential for neural communication because the electrical signal that passes through the neuron depends on maintaining an electrical difference between these two fluids.

Membrane Potential
A neuron's outer surface is a barrier that allows some charged particles (ions) to pass through more easily than others. What is the most direct and significant consequence of this selective passage?
A neuron's outer boundary allows some substances to pass through while actively restricting the movement of others, particularly those with an electrical charge. What is the most direct and critical outcome of this selective filtering property for the neuron's electrical function?
