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:

  1. Most Spinal Cords are about 18 inches long.
  2. I am about as thick as a man's little finger.
  3. The Spinal Fluid acts as a cushion for the Spinal Cord to protect the cord from damage
  4. I contain over 10 million Nerve Cells
  5. My base has a cluster of nerves, which are the most sensitive in all of the Spinal Cord.

  • Facts about my Department

  1. If you lined up all the neurons in your body, it would be around 600 miles long.
  2. Neurons are the longest cells in the human body, and can be up to three feet long.
  3. The Nervous System can transmit impulses as fast as 100 meters per second.
  4. The left side of the human Brain controls the right side of the body, while the right side of the Brain controls the left!
  5. Only four percent of the Brain's cells work at a time, while the rest are kept on reserve.

The Interdependence of the Spinal Cord

Two of my co-workers in the Nervous Department, the Brain and the Central Nervous system, rely on me heavily. Their jobs differ from mine, and I do not govern their actions, but both have equally important jobs in this body- the Brain directs all activities in this body, and the Central Nerves send the messages throughout the body on how to cooperate and coordinate all the systems together. Without me, however, the Brain would not be able to send the signals near as efficiently, as I am the main nerve trunk, and the Central Nerves would not receive most of the messages from the Brain. ( Our circle of effort would collapse, and surely would send all other systems into chaos. Eventually, without me, the body would develop paralysis- or, in other words, complete immobility.

Alternative Solutions

There are several disposable organs within the body, such as the appendix. Another solution would be to lay off only one organ within a pair- for example, one kidney instead of both or a single one in comparison to one. Firing expendable organs would not effect the other Departments or the Human's health, making it so that the company could carry on just as it had.

Thank you for reading, and I hope you take my presentation into consideration.
