the channels that have closed have to undergo a refractory period

Nothing. The action potential will propegate from the point where depolarization occurs in either direction. The receptors that normally trigger the action potential are located at one end. The repolarization time prevents reactivation of a channel until the action potential is completed.

The main answer is the existence of Refractory Period. As Na+ entered through Na+voltage channel, value of potential become more positive. at certain point (as Na+ almost reached the max value of its potential (around +30mV i think..)). The graph (i hope you understand which graph) then become a slope downward toward negative value.. this shows the Na+ voltage gate become inactive & no Na+ ions can enter the cell (nerve or non nerve cells) during this period. And it takes a milisecond for the gate to become depolarise again.. oh, sorry i forget. it also got to do with the Na+ voltage gate itself- the gate is a protein, which has 'cover' that control Na+ flow into cell.

No they will not move backwards, but if you were to say start an impulse from the middle of an axon it will travel in both directions from the starting point.

There is a lot to suggest that brain neurons form around quantum energy threads. Not the other way around. The physical encasing the spiritual or energy body. :) Yes, 328hz is the frequency surgeons are using to repair damaged dna. Practicing Shaman... quantum physics rocks
