Answer» Na+ ions from extracellular fluid to INTRACELLULAR fluidExplanation:Action potential in a nerve is formed DUE to opening of Na + channels of the axonal membrane which results in movement of Na + ions inside the axonal cytoplasm.During resting state the axonal membrane is NEARLY impermeable to Na + ions and more permeable to K+ ions.So in the cytoplasm there is K+ concentration and in the external fluid there is Na+ ion concentration.When stimulus is applied then the Na+ ions move inside the AXON generating action potential .I HOPE THIS IS HELPFULTHANKS |
