  • The inside of the axon becomes more negative than outside tissure fluid and an equalibriam is established. 

2) DEPOLARISATION 

  • The stimulus causes a change in charge. If this reaches the threshold needed to open the voltage-gated sodium channels an action potential can occur. 

3) DEPOLARISATION 

  • Sodium channels change shape…
