2. A variety of evidence indicates that sodium channels in the axon are closed at resting potential (for the purpose of this question, assume that they all are).
Yet when we test this hypothesis by increasing the sodium concentration
outside of the cell, we consistently evoke an action potential. Explain why this
occurs.
