What are the different functions of the nervous system?

The nervous system functions are too numerous to be able to state in its entirety. This is because the nervous system plays a role in most things that occur in the body. Without it, people would not have thoughts, much less thoughts that are better than other animals. In addition, this system is controlled by organs such as heart and pancreas. The nervous system is also responsible for interpreting information from the senses and transmitting messages in response.

In order to understand the function of the nervous system, it is useful to have a general idea of ​​how it works. Simply put, there are nerves all over the body that connect to the spinal cord, and the spinal cord connects to the brain. Information travels nerves, spinal cord and to the brain where it is processed. The brain then sends signals or challenges along the same path and causes some type of action. The from the open system can be considered an command and a control center. In order to work other systems, they need instructions that come from the brain and travel to the spinal cord. For example, the heart would not know when and how no these instructions wouldEagle blood, and muscles would not receive signals to withdraw so that one can move.

Interpretation of information derived from the senses is another of the main functions of the nervous system. Without it, the senses would be practically unnecessary. For example, consider feeling. Without the role played by the central nervous system, one can suffer from a wound, but does not have the ability to interpret the feeling of pain as a need to seek medical care.

Also consider the feeling of the smell and a person who is exposed to smoke in a burning building. Without the central nervous system, one could not identify the odor. There would also be no resources to send signals to motivate a person to leave a place for safety.

Although other animals have a nervous system, they do not compare to those people. This can be seen by analyzing one of the functions of the nervous system that can be easily taken for granted - generally high level of thoughtof it. This is because of the complexity of the human nervous system that humans are generally smarter and more capable than other animals.
