  • This amazing system is a vast network of fibres which enables the brain to communicate with the body's organs and systems
  • Billions of electrical and chemical signals are transmitted around this network both to and from the brain.
  • The system is split into central nerves and peripheral nerves.
  • Together they form a network that spreads around the entire body.
  • The central system is made up of the brain and spinal cord.
  • The nerve fibres that branch out from the central nerves form the peripheral system.
  • The peripheral nerves send information back to the central nerves for processing.
  • Some nerves in the peripheral system are grouped together to keep close control over vital organs and functions.
