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.
