such as with the career of neurologists, how come both parts are relatedt? How does the spinal cord work with the brain?

[Luton]

There are a huge amount of nerves in the spinal cord that lead to the brain. That is why if you can be paralyzed if you injure your spinal cord.

[Master Chief]

Well it carries messages from the brain to the rest of the body its the central nervous system if you get really badly injured in that area paralysis or worse

[Kerri G]

All sensory receptors in our body (pain, touch, taste, etc) are relayed through the spinal cord to the brain, and then this information is processed in the brain and sent back through the spinal cord to illicit the appropriate response. The spinal cord is basically a bunch of nerves, which helps the brain relay messages throughout the body. Very few decisions made by the brain can be carried out without the spinal cord.

The brain and the spinal cord together make up the central nervous system. The spinal cord is literally an extension of the brain; the neurons that run down the spinal cord all originate in the brain.To oversimplify horribly, a neuron is a cell that sends electrical signals. The body of the neuron may be in the cortex of the brain (the folded surface on the outside of the brain) or in deeper areas of the brain called nuclei. The neuron will have a long arm called an axon, down which signals can be sent. It's some of these axons that exit the brain, group together in what are called the pyrimidal tracts or corticospinal tracts, and make up a good portion of what becomes the spinal cord. They also cross over (decussate) at a place in the brain stem called the medulla and that, incidentally, is why the right half of your brain controls the left side of your body and vice versa.There's a lot more to it than that, of course, but I hope that answers your question generally. *g*

The Brain and Spinal Cord are a major part of your nervous system.
The average human brain weighs about 1,400 grams (3 lb). When the brain is removed from the skull, it looks a bit like a large pinkish-gray walnut. The spinal cord is a thick white cord of brain cells that runs down the backbone
