Place in the correct order of a nerve impulse.
= propagation of the action potential, depolarization of the proximal membrane causes permeability changes in the adjacent membrane
= stimulus initiates local depolarization; the membrane's polarity is changed due to Na rushing into the neuron
= resting membrane is polarized; extracellular ion is Na, chief intracellular K
= initial ionic resting conditions restored
= repolarization; K diffuses out of the cell, restoring negative charge on the inside of the membrane and the positive charge on the outside
=depolarization and generation of an action potential, membrane polarity completely reversed
