Answer
At resting potential,
ions are primarily outside the neuron, and
ions are primarily inside the neuron.
Explanation
At resting potential, the distribution of ions across the neuronal membrane is crucial for maintaining the electrical charge difference. Sodium ions (
) are primarily found outside the neuron, while potassium ions (
) are primarily found inside the neuron. This distribution is maintained by the sodium-potassium pump, which actively transports
out of the cell and
into the cell, against their concentration gradients. This creates a negative charge inside the neuron relative to the outside.
