During the propagation of a nerve impulse, the action potential results from the movement of:

1. K+ ions from extracellular fluid to intracellular fluid

2. Na+ ions from intracellular fluid to extracellular fluid

3. K+ ions from intracellular fluid to extracellular fluid

4. Na+ ions from extracellular fluid to intracellular fluid

Depolarization of axolemma during nerve conduction takes place because of:
 

1. Equal amount of Na+ & K+ moves out across axolemma
2. Na+ ions move inside
3. More Na+ ions are outside
4. None of the above
