Some people cannot move their arms and legs from the neck down. This is called Quadriplegia. It usually happens after an accident or something that hurts the spinal cord.

The spinal cord is like a highway of messages between the brain and the body.When it gets damaged, the messages can’t travel down anymore.

It’s a bit like a broken lamp: when the bulb is out, the electricity can’t turn on the light. In quadriplegia, the “body’s electricity” can’t turn on the muscles.
