Verified step by step guidance

Understand the concept of the resting membrane potential in neurons, which is the electrical potential difference across the neuron's plasma membrane when the neuron is not actively sending a signal.

Recognize that during the resting state, the neuron's membrane is polarized, meaning there is a difference in charge between the inside and outside of the cell.

Identify the role of ion channels in maintaining the resting membrane potential. Specifically, focus on the voltage-gated Na+ (sodium) and K+ (potassium) channels.

Recall that during the resting state, the voltage-gated Na+ and K+ channels are typically closed. This prevents the movement of these ions across the membrane, helping to maintain the resting potential.

Conclude that the statement 'All of the voltage-gated Na+ and K+ channels are closed' best describes the resting membrane state in the neuron, as it reflects the condition necessary to maintain the resting membrane potential.
