MS is a disease that people get in parts of the body called the ‘central nervous system’.

These parts include the brain, the spinal cord that goes down the neck and back, and millions of ‘nerve fibres’ that run through our bodies.

Nerve fibres are like tiny telephone lines sending messages from your brain to different parts of your body.

For example:

“Come on legs and arms, time to dance like Justin Timberlake”,

“Hurry up tongue, lick the ice-block before it drips all over my hand”,

or “Ouch! That crab just nipped my little toe!”
