Why Is The Nervous System Important: An Overview

Our nervous system is made up of nerve tissue. Humans could not function without the nervous systems. Neurons are the cells that make up nervous tissue. They allow electrical nerve signals to be sent by the body. Neurons assist us in interpreting stimuli, controlling muscle contractions, as well as coordinating various bodily functions. Moreover, the nervous system is responsible for our awareness, ability to remember, reason and express complex emotions.

The brain is the most important component of the nervous system. These organs are referred to as the “central nerve system” because they are so important to our existence. We have the skull and the spine to protect and surround the central nervous systems. Peripheral nerve system includes any other nerves, ganglia or structures outside of the spine and brain. The peripheral nerve system connects the central nervous with other parts of the body. The peripheral nervous can be further subdivided to the somatic nerve system and autonomic system. Somatic nervous systems are responsible for allowing us to move our muscle voluntarily. The autonomic system, in contrast, is largely automatic and controls breathing, heartbeat, and many other body functions.

In the event that I ever get into a car accident and need to speak with medical personnel, understanding the nervous system’s functions will make it easier for me. In the event that I lose feeling on one side of my body or limb, I will be able to help medical personnel determine where it originated. Now I know how to deal with potential head, spine and neck injuries.
