The long spinal cord is the main pathway for nerves so it is apart of the nervous system.

There are many parts to the spinal cord and they include the brain, which sends messages to the body. The boney vertebrae (vertebral column) surround the spinal cord, giving it protection. Another part of the spinal cord is the spinal nerves, which connects to a body part or organ.

The brain sends millions of messages to all parts of the body; the spinal cord gets the message there. The message is sent from the brain, and then travels down the spinal cord until it reaches the spinal nerves. Spinal nerves connect to the body part or organ that the message intends to reach. The message then shoots off the spinal nerves until it reaches its destination.

A working spinal cord helps us to move. It sends messages to every part of the body telling it what to do. It does this all the time, even when you’re sleeping. The spinal cord helps your reflexes and lets your body recognise hot, cold or sharp. Also, the spinal cord senses the position of your arms and legs.

In an adult man’s body the spinal cord is about 45cm long and in an adult woman’s it is about 43cm long. When your body is cold in winter your spinal cord is what reacts and causes your skin to form goose bumps, which tells you are cold. Did you know that both a giraffes and humans body has seven vertebrae? And, a human’s spinal cord is made up of 33 bones in total.

People need a working spinal cord to ambulate/move; it helps your brain tell your body things. You may get paralyzed if you damage it so it is a vital part of your body and the nervous system. The spinal cord is an automatic function, like your heart it just keeps working, until your body shuts down.
