3 Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 5 Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. 4 Discuss the relative permeability of the membrane to Na+ and K+ in a resting neuron.

Step 1
The resting membrane potential is primarily determined by the concentration gradient of potassium ions (K+) and the permeability of the membrane to K+ ions. In a resting neuron, the membrane is much more permeable to K+ ions than to sodium ions (Na+). This is due Show more…

Why does a cell with a resting membrane potential of -70mV that becomes less permeable to potassium ions (K+) depolarize (Eion = -90mV)? Explain your answer. Consider the squid giant axon at rest with normal intracellular and extracellular ion concentrations. If the membrane permeability to K+ ions is increased, the K+ equilibrium potential (Nernst potential) stays the same. Why is this?

1: Describe the changes in the neuron membrane that occur throughout the course of an action potential. 2: Mention: Resting state, threshold, depolarization, repolarization, and hyperpolarization. 3: mention how the action potential is related to neuron communication.
