What is Nervous System and How it Works: Explain with Concept Map

Last updated on April 7, 2021 by

The nervous system is one of the most complex systems in the body of both humans and animals. It is responsible for transmitting signals from the brain to various body parts for them to function. Body coordination, and sensory functions are also dependent on the nervous system. On that note, we can therefore say that the nervous system is an important part of the body. With that being said, we created some nervous system concept map to further explain what this system is all about.

Nervous System and its main functions

The nervous system is the one responsible for the movements or motor skills of the entire body. This means that voluntary and involuntary movements are all transmitted from the brain through the nervous system. Aside from that, it has control over other body organ systems since it houses the brain, which is the control center of a living body. To understand the other functions of the entire nervous system, refer to the central nervous system concept map above.

Parts of the Nervous System

As we may all know, a system consists of various parts that complements each other. This is also the case for the nervous system, as it comprises of organs that have their own specific functions. Starting with the Brain, followed by the Spinal Cord, these makes up the Central Nervous System. Aside from that, there is also the Peripheral Nervous System which comprises of all the nerves in the body. These organs all work hand-in-hand to manage the overall motor and sensory skills of the entire body. To see further understand, you can look at the divisions of the nervous system concept map above to see the organs that makes up the entire nervous system.

3 Types of Nerves and Subsystems

As the name suggests, the nervous system comprises mainly of nerves. These are small cord-like structures that runs all over the body. Nerves are generally responsible for carrying out electrical impulses from the brain to the target body organ. Nerves are divided into three types namely the Autonomic nerves, Motor nerves, and the Sensory nerves. The nervous system concept map above explains the functions of each type, and their responsibilities in the body.

  • Autonomic Nerves System – This sub-system is responsible for regulating involuntary physiological processes such as heart beat rate, blood pressure, digestion and respiration.
  • Motor Nerves – These nerves are the one that executes voluntary body movements from the brain, to the target organs. The process starts with the brain, which then passes through the spinal cord, and is received by the receptors on each body organs.
  • Sensory Nerves – These nerves are the one responsible for our senses. The process starts with the environment or external stimulus, which is then carried by the nerves to the brain, as seen on the central nervous system concept map above, which then interprets the sensation and tells your what it is. In-general, you feel pain and other sensations because of the sensory nerves in your body.

Central Nervous System and Peripheral Nervous System

As seen from the map above, there are two subsystems within the nervous system. These are classified into the Central Nervous System which consists of the brain and spinal cord, and the Peripheral Nervous System consisting of all the nerves within the body. Based on their name, we can already identify which is important. However, one can’t exist without the other. On that note, let’s study the divisions of the nervous system concept map above to learn the difference between the two.

  • Central Nervous System(CNS) – This is the center of operations in the entire Nervous system. This is because the brain is a part of this system, which is the control center of the entire body. The central nervous system is the one who executes orders and interprets sensation for the entire body.
  • Peripheral Nervous System (PNS) – The supporting system of the CNS, the Peripheral Nervous System makes up almost the entire Nervous system. This is because this subsystem runs across the entire body since the nerves that delivers electrical signals from the brain are part of it. To simplify things, the PNS is the logistics department of the entire nervous system, and receives order from the Central Nervous System.

Conclusion

Definitely one difficult topic to talk about, the Nervous System surely one thing that you should know about. Hopefully, the Nervous System concept maps above all were helpful in your study. You can also add information that you think were beneficial by clicking the buttons above.
