Spinal Cord: What to Know

Here are some things you should know about the spinal cord:

- The spinal cord is a long, thin, cylindrical bundle of nervous tissue that runs from the brain down the back.

- It is protected by the vertebrae of the spine.

- The spinal cord carries messages between the brain and the rest of the body.

- It is also responsible for controlling some of the body's automatic functions, such as heart rate and breathing.

- The spinal cord is divided into two parts: the gray matter and the white matter.

- The gray matter is located in the center of the spinal cord and contains the cell bodies of the neurons.

- The white matter is located on the outside of the spinal cord and contains the axons of the neurons.

- The spinal cord is a very important part of the nervous system and any damage to it can have serious consequences.

Here are some additional facts about the spinal cord:

- The average spinal cord is about 45 centimeters long.

- It is made up of about 31 million neurons.

- The speed of nerve impulses through the spinal cord is about 120 meters per second.

- The spinal cord is responsible for reflexes, which are involuntary muscle contractions that occur in response to a stimulus.

- The spinal cord is also involved in the regulation of blood pressure, body temperature, and digestion.

- Damage to the spinal cord can cause paralysis, loss of sensation, and difficulty breathing.

- The spinal cord is a very complex structure and scientists are still learning new things about it all the time.
