2.84 Electrical Impulses


  • The messages that nerves carry are called the nerve impulses and they are electrical signals.
  • They pass along quickly along the axon of the neuron.
  • Some axons have a fatty sheath around them which insulates the axon and allows the impulse to travel faster along the axon.
