  • At resting potential there is positive charge on the outside of the membrane and negative charge on the inside,with high sodium ion concentration outside and high potassium ion concentration inside.


  • when stimulated,voltage-dependent sodium ions channels open,and sodium ions flow into the axon,depolarising the membrane. Localised electric currents are generated in the membrane.sodium ions move to the adjacent polarised region causing a change…
