The Nervous System

By: Mackenzie, Giselle, and Jeb

The Function

The Nervous System consists of fibers that start from the brain and reach across every part of the body. The neurons are nerve cells that are all over your body. "Neurons send signals to other cells through thin fibers called axons, which cause chemicals such as neurotransmitters to be released at junctions called synapses, the NIH noted," (Zimmermann, By Kim Ann. "Nervous System: Facts, Function & Diseases."). A synapse can give a command to a cell and finish the entire communication process in the fraction of a millisecond. The Nervous System sends signals all throughout your body to tell the rest of your body what to do. If you want to raise your arm or move a part of your body, your nerves send a command to your brain to raise your arm. If you fall and are bleeding, your nerves send a signal to your brain telling you that you are bleeding and it hurts. Without the nervous system you would not be able to know if something is wrong in your body or if you are critically injured. The nervous system is a very important part of your body.

Other Systems that Work with The Nervous System

One of the systems that works with the Nervous System is the Endocrine System. This system helps us to create hormones and enzymes. "The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things," (livescience). The Endocrine system also works with the brain to help us move and speak. Another system the Nervous System works with is the brain. Without the brain, we would be dead first of all, but we would also not be able to move or speak, or frankly do anything. Withou8t these systems working with the Nervous System we would not be able to produce certain hormones and enzymes, move, or speak.


Nerves detect the changes both internal and external of the body. They collect information and transmit them to the brain. As it transmits to the brain it goes to the effector organs. The nervous system also consists your spinal cord. The spinal cord mostly works with the brain. The spinal cord consists bundles of neurons sending information to your brain.

Medical Advances

You can repair your nervous system using stem cells. Scientists were able to repair nerve damage using stem cells deprived from an adult human muscle tissue on a mouse to restore its function.Then the stem cells divide into neurons and support cells. Then the myelin sheath around the axons of neurons improving the conduction of the nervous system
