Q. No.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

Hints
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 |
