Question

Quizplus · Accepted Answer

The outside of a neuron cell membrane typically has a higher concentration of sodium ions (Na+) compared to the inside, and it is more positively charged due to the distribution of ions across the membrane. This difference in charge and ion concentration is crucial for the generation and propagation of electrical signals in neurons.
