How Does the Human Nervous System Actually Work in Practice

With around 86 billion nerve cells in the brain alone, the nervous system is a vast and complicated biological system.

But this system also plays a vital role in managing and regulating the human body. And since your health and wellbeing can influence this system, it’s important to know how to look after it. 

Keep reading to learn more about the human nervous system and how it works. 

What Is the Nervous System?

The nervous system is the command center of your body. It is made up of nerves that gather information from your senses and control your movements through commands from your brain. 

There are two parts to the nervous system. The brain and spinal cord make up the central nervous system. The peripheral nervous system is made up of nerves, organs, and muscles.

How the Nervous System Works

Your nervous system has two networks: your autonomic nervous system and your somatic nervous system. Your autonomic nervous system is responsible for your involuntary actions like organ function and reflexes. Your somatic nervous system is responsible for planned functions like voluntary movement. 

There are two types of nerves in your body. Nerves that are connected directly to your brain are cranial nerves, while those connected to your spinal cord are spinal nerves. The vagus nerve is a cranial nerve and is the longest in the body.

There are three types of neurons or nerve cells. There are sensory nerves that receive signals and send them to your brain, and there are motor nerves that receive signals from your brain and move your muscles. Interneurons carry messages between the two.

Keeping the Nervous System Healthy

If you want your nervous system in optimal health, you need to look after your mental and physical health. The best way to physically look after your nervous system is to eat healthily, exercise, and avoid dangerous substances. 

Good mental health is also important for your nervous system to work efficiently. A lot of mental illnesses lead to disruptions in the brain’s chemistry. This can influence how well the neurons work because it slows the communication between the neurons in the nervous system.

The vagus nerve is one of the most influential nerves in your nervous system. You can regulate your nervous system by treating your vagus nerve with stimulation. Learn more about this at

Damage to the Nervous System

Toxic substances and certain diseases can permanently damage your nervous system. To avoid permanent damage, you should take precautions against risky behavior and illnesses.

As you get older, your nerves are slower to send signals. This can make you feel weaker or lose sensation in your fingertips and toes. This is also why your reflexes get slower as you age. 

Knowing The Human Nervous System

Knowing how the human nervous system works means you’re able to look after it. You can recognize when it needs support and how to keep it healthy.
