  • 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.
