Question

Quizplus · Accepted Answer

In the resting state of a neuron, the fluid outside the neuron (extracellular fluid) has a high concentration of positive sodium ions (Na+). This creates a difference in ion concentration across the neuron's membrane, which is crucial for the neuron's ability to generate an action potential.
