Semipermeable Membrane
A neuron's outer surface is composed of a semipermeable membrane that acts as a selective barrier. It allows smaller molecules and those lacking an electrical charge to pass through freely, while restricting the movement of larger molecules or those with a high electrical charge.

A neurological disorder is characterized by a significant slowing of the electrical signal as it travels down the long extension of a nerve cell, leading to symptoms like muscle weakness and poor coordination. Given this information, which part of the nerve cell is most likely deteriorating?

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?
