9 Things About Nerves that Will Shock You



The nervous system is one of the most important parts of our body. It consists of the brain, spinal cord and nerves. The purpose of the nervous system is to regulate your body's internal communication and adapt to different outside stimuli.


The nervous system interacts with our skin, joints and muscles. When we are feeling pain, the affected area releases chemicals that are felt by our nerves. The nerve pathway transmit that information to our brain. The brain then sends communication back down to the affected area in an attempt to reduce or ease the pain sensation.


There has been a lot of scientific research conducted about our nervous system. There are also a lot of over the counter products created to combat nerve pain. You can find out about Nerve Pain Remedies and common symptoms online. Consult your doctor or physician before taking any medication, especially if you have any pre-existing health conditions to be concerned about.


Here are 9 things about nerves that will shock you:

1. The nervous system is divided into two parts.

Our body's nervous system is actually composed of two parts: the central nervous system and the peripheral nervous system. The central nervous system is in our skull and our spine's vertebral canal. It includes all of the nerves in the spinal cord and brain. The peripheral nervous system consists of all other nerves in our body.

2. The two parts of our nervous system have both voluntary and involuntary parts.

Both the central and peripheral nervous system have voluntary and involuntary parts. These parts are linked in the central nervous system, but are not linked in the peripheral nervous system.


Voluntary parts of our nervous system control the actions that we can purposely control, such as the movement of our arms and legs, head, neck and other parts of the body. Involuntary parts of our nervous system control things such as our breathing, heart rate and metabolism. These processes are done automatically and are crucial for our survival. The involuntary parts of the peripheral nervous system appear in different parts of the body, and include the enteric, sympathetic and parasympathetic nervous systems.

3. Our body has billions of nerve cells.

Our bodies contain billions of nerve cells also referred to as neurons. There are about 100 billion neurons in the brain and over 10 million neurons in the spinal cord. There are more neurons in our bodies than there are stars in the Milky Way. Neurons send electrochemical energy signals to other neurons in the body. Some of those transmissions can take place at over 100 miles per hour.

4. Neurons may look different depending on their function.

Not all neurons look or act the same. Motor neurons have a cell body on one end, dendrites on the other end and a long axon in the middle. Sensory neurons have dendrites on both ends that are linked by a long axon that has a cell nucleus in the middle.

5. Neurons are programed for different functions.

There are four kinds of neurons:

- Interneurons send messages from one neuron to another.

- Motor neurons send signals from the central nervous system to other parts of the body.

- Sensory neurons deliver signals from the skin, glands and muscles to the central nervous system.

- Receptor neurons respond to sound, light, touch and chemical interaction around you and convert that response into electrochemical energy that is transmitted by sensory neurons to the central nervous system.

6. The sympathetic nervous system prepares our body for action.

When you are getting ready for physical activity, your sympathetic nervous system is at work. It's busy telling your body to open your airways to allow more air to come in and to increase your heart rate. It also tells your body to temporarily stop digestion so that it can focus on the activities at hand.

7. The parasympathetic nervous system controls the body at rest.

When you are ready to rest after your workout, your parasympathetic nervous system comes into play. It controls bodily functions when you are at rest. Activating your metabolism and digestion and helping the body stay at rest are some of the parasympathetic nervous system's primary functions.

8. The enteric nervous system controls your bowel movements.

The enteric nervous system is a separate nervous system specifically for digestion and your bowel. It helps to regulate digestion and bowel movements. An underrated but very important of your body's nervous system.

9. There are ways to alter your nervous system.

Scientists have been working for years on various ways to "hack" the body's nervous system. They attempt to control cells in the body with flashes of light. These flashes of light program the cells to react by way of genetic altering. These processes have helped scientists examine how different types and groups of neurons function. They have also conducted experiments in attempts to activate brain cells and observe how that activation impacts other areas of the body.


The nervous system is very complex and fascinating. The nervous system cannot exist without sodium or potassium ions. Vitamin B is a good source of these ions, as well as red meat, poultry, milk, beans, nuts, green vegetables and fruits.


Our nervous system does many things every day that we often take for granted. It helps us react to light, sound, and other sensations. It tells our hearts to keep beating and pumping blood through our complex network of arteries and veins. It transmits signals when we feel aches and pains. It increases metabolism when we are active and lowers metabolism when we are at rest. It aids in our digestion and endocrine system.


The nervous system has many independently operating parts that all work as part of a team. Millions of cells and nerve endings are sending signals and cooperating with one another. They help to interpret what we see and feel. When nerves are damaged, they can affect our ability to feel pain or distress. That's why it's important to have a healthy nervous system. It keeps our body running smoothly and efficiently.
