The Structure of the Spinal Cord

Protection Comes First
Your Spinal Cord is fragile. So it has protection. A lot of protection. Your backbones called vertebrae surround it. This is like a flexible suit of armor. There are also three layers of tissue called meninges. The whole structure of Spinal Cord is built for safety.
The Inner Parts
Inside the Spinal Cord are two main types of tissue. White matter and grey matter. The grey matter is the core. It processes information. The white matter is the highway. It sends the signals fast. This design makes the Function of Spinal Cord very efficient.
The Nerves
Spinal nerves exit the Spinal Cord. They go to every part of your body. Your arms. Your legs. Your organs. These nerves are the roads that leave the main highway. This is how the brain and body talk. The number of these nerves in the structure of the spinal cord is amazing.

Quick Reflexes
