Which of the following help to set the resting potential of a neuron? (Select all that apply) The permeability of the membrane to potassium ions. The activity of the sodium/potassium pump. The concentration of potassium ions inside and outside the cell. The concentration of sodium ions inside and outside the cell. The permeability of the membrane to sodium ions.

When the cell is NOT sending signals, the electrical difference between the inside and outside of a neuronal membrane is specifically referred to as the resting membrane potential. The differences in relative concentrations of ions inside and outside the cell act as an electrical force. The specific ion(s) MOST important to establishing the resting potential in neurons would be: Na+ K+ intracellular anions (e.g. proteins) H+ Na+, K+, and intracellular anions are all important.
Which of the following contribute to resting membrane potential in a neuron cell? (SELECT ALL THAT APPLY) - Increased permeability to Na+ across the neuron cell membrane - Increased permeability to K+ across the neuron cell membrane - Baseline differences in ion concentration between the ICF and ECF: higher K+ outside of the cell and higher Na+ inside - Many Na+/K+ pumps on the surface of the neuron cell membrane - Many leaky Na+ channels on the surface of the neuron cell membrane - Baseline differences in ion concentration between the ICF and ECF: higher Na+ outside of the cell and higher K+ inside
