The Spinal Cord- Nervous Department
By: Bri Taylor
General Facts About my Job
- Physical Descrip., Location, Purpose and Importance:
I am a long chain of flat bones, connected by one long nerve, that runs from the base of the brain to the lower back. I am located in the Human's back.
I support the body, and serve as the main nerve trunk by sending most of the Brain's messages throughout the Human. Without a Spinal Cord in the Nervous system, the body would collapse- crushing many important organs in the Respiratory, Circulatory, and Digestive Department- and the nerves would only receive few messages from the Brain.
- Facts About my Job and Department:
- Most Spinal Cords are about 18 inches long.
- I am about as thick as a man's little finger.
- The Spinal Fluid acts as a cushion for the Spinal Cord to protect the cord from damage
- I contain over 10 million Nerve Cells
- My base has a cluster of nerves, which are the most sensitive in all of the Spinal Cord.
- Facts about my Department
- If you lined up all the neurons in your body, it would be around 600 miles long.
- Neurons are the longest cells in the human body, and can be up to three feet long.
- The Nervous System can transmit impulses as fast as 100 meters per second.
