GENERAL

• WHAT REMAINS THE SAME ABOUT AN ACTION POTENTIAL?

  action potential stays same size always
• HOW DOES AN ACTION POTENTIAL WORK?

  one part of the axon produces an action potential and becomes depolarised acting as a stimulus for depolarisation of the next region of the axon
• VALUE FOR WHEN THE AXON IS POLARISED?

  -65 mV
• VALUE FOR WHEN THE AXON IS REPOLARISED?

  -65 mV
• VALUE FOR WHEN THE AXON IS DEPOLARISED?

  +40 mV
• VALUE FOR WHEN THE AXON IS HYPERPOLARISED?

  -95 mV
