Introduction

The nervous system is a complicated biological system made up of a network of many nerves. Signal transmission and reception are controlled by the nervous system throughout the body.

The action potential is a sudden and rapid change in the resting membrane potential (RMP) caused by the activation of neurons. When electric impulses travel down the axon towards the axon terminal, neurotransmitters are released, inhibiting or excitatory postsynaptic cells.
Action Potential occurs through 3 phases that include:

  • Depolarization
  • Repolarization
  • Hyperpolarization
