6 Ways to Strengthen Your Nervous System
Your eyes may watch as your best friend walks toward you — but without the brain, you wouldn't even recognize her. In the United States, alcoholism is a common cause of folic acid deficiency. It is essential that you pamper yourself sometimes because the pleasurable experience, of course, is better for your body than a stressful one. Information collected by the five senses comes into the brain from the spinal cord to the cortex. Dried tart cherries make delicious additions to meals and snacks. It is because omega-3 fatty acids are beneficial in the proper neuron functioning and improving nerve transmissions.

They're both cushioned by layers of membranes called meninges as well as a special fluid called cerebrospinal fluid. This fluid helps protect the nerve tissue, keep it healthy, and remove waste products. The forebrain is the largest and most complex part of the brain. It consists of the cerebrum — the area with all the folds and grooves typically seen in pictures of the brain — as well as some other structures beneath it. The cerebrum contains the information that essentially makes us who we are: Specific areas of the cerebrum are in charge of processing these different types of information.

These are called lobes , and there are four of them: The cerebrum has right and left halves, called hemispheres , which are connected in the middle by a band of nerve fibers the corpus callosum that enables the two sides to communicate. Although these halves may look like mirror images of each other, many scientists believe they have different functions. The left side is considered the logical, analytical, objective side.

The right side is thought to be more intuitive, creative, and subjective. So when you're doing a math problem you're using the left side, and when you're listening to music you're using the right side.

Scientists think that some people are more "right-brained" or "left-brained" while others are more "whole-brained," meaning they use both halves of their brain to the same degree.

The outer layer of the cerebrum is called the cortex also known as "gray matter". Information collected by the five senses comes into the brain from the spinal cord to the cortex. This information is then directed to other parts of the nervous system for further processing. For example, when you touch the hot stove, not only does a message go out to move your hand but one also goes to another part of the brain to help you remember not to do that again.

In the inner part of the forebrain sit the thalamus , hypothalamus , and pituitary gland. The thalamus carries messages from the sensory organs like the eyes, ears, nose, and fingers to the cortex.

The hypothalamus controls body temperature, thirst, appetite, sleep patterns, and other processes in our bodies that happen automatically. It also controls the pituitary gland, which makes the hormones that control our growth, metabolism, water and mineral balance, sexual maturity, and how we respond to stress. The midbrain, located underneath the middle of the forebrain, acts as a master coordinator for all the messages going in and out of the brain to the spinal cord.

The hindbrain sits underneath the back end of the cerebrum, and it consists of the cerebellum, pons, and medulla. The cerebellum — also called the "little brain" because it looks like a small version of the cerebrum — is responsible for balance, movement, and coordination. The pons and the medulla , along with the midbrain, are often called the brainstem.

The brainstem takes in, sends out, and coordinates all of the brain's messages. It is also controls many of the body's automatic functions, like breathing, heart rate, blood pressure, swallowing, digestion, and blinking. The basic functioning of the nervous system depends a lot on tiny cells called neurons.

The brain has billions of them, and they have many specialized jobs. For example, sensory neurons take information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain and back to the rest of the body. All neurons relay information to each other through a complex electrochemical process, making connections that affect the way we think, learn, move, and behave.

When you learn things, messages travel from one neuron to another, over and over. Then the brain creates connections or pathways between the neurons, so things become easier and you can do them better and better. In young children, the brain is highly adaptable. In fact, when one part of a young child's brain is injured, another part may learn to take over some of the lost function.

But as we age, the brain has to work harder to make new neural pathways, making it more difficult to master new tasks or change established behavior patterns. That's why many scientists believe it's important to keep challenging your brain to learn new things and make new connections — it helps keep the brain active over the course of a lifetime. Memory is another complex function of the brain. The things we've done, learned, and seen are first processed in the cortex, and then, if we sense that this information is important enough to remember permanently, it's passed inward to other regions of the brain such as the hippocampus and amygdala for long-term storage and retrieval.

As these messages travel through the brain, they create pathways that serve as the basis of our memory. Different parts of the cerebrum are responsible for moving different body parts. The left side of the brain controls the movements of the right side of the body, and the right side of the brain controls the movements of the left side of the body. When you kick a soccer ball with your right foot, for example, it's the left side of your brain that sends the message allowing you to do it.

A part of the peripheral nervous system called the autonomic nervous system is responsible for controlling many of the body processes we almost never need to think about, like breathing, digestion, sweating, and shivering. The autonomic nervous system has two parts: The sympathetic nervous system prepares the body for sudden stress, like if you see a robbery taking place.

When something frightening happens, the sympathetic nervous system makes the heart beat faster so that it sends blood more quickly to the different body parts that might need it.

It also causes the adrenal glands at the top of the kidneys to release adrenaline, a hormone that helps give extra power to the muscles for a quick getaway. This process is known as the body's "fight or flight" response.

The parasympathetic nervous system does the exact opposite: It prepares the body for rest. It also helps the digestive tract move along so our bodies can efficiently take in nutrients from the food we eat. Your eyes may watch as your best friend walks toward you — but without the brain, you wouldn't even recognize her.

Pepperoni pizza sure is delicious — but without the brain, your taste buds wouldn't be able to tell if you were eating pizza or the box it came in. None of your senses would be useful without the processing that occurs in the brain. Because the brain controls just about everything, when something goes wrong, it's often serious and can affect many different parts of the body.

Inherited diseases, brain disorders associated with mental illness, and head injuries can all affect the way the brain works and upset the daily activities of the rest of the body. A tumor is an abnormal tissue growth in the brain.

Doctors recommend consuming magnesium-rich foods such as:. You can also take magnesium supplements. In this case, take three grams every day three times a day so the body can absorb it properly. You can make teas with them, take them as supplements, use them as air fresheners in your home, or apply them to your skin as essential oils:. Sunlight is an excellent nervous system regulator and also provides vitamin D.

To benefit from it, you can sunbathe for 10 to 15 minutes every day, preferably in the mornings or late afternoons. In addition, it helps eliminate electromagnetic radiation that we absorb from continuous contact with electronic devices. Avocados are a delicious and nutritious fruit that are wonderful for your health. Avocado remedies have become very popular among people who seek out a healthier lifestyle.

Avocados are a unique kind of fruit. Having a toothache is really uncomfortable. Any time one appears, it can instantly ruin your day.
