What is the function of the nerves

All the external information that we constantly receive (from sunlight to cold) are stimuli that are captured by our body thanks to the nervous system. Most of the reactions that our body makes when interacting with the external environment are thanks to this system that is in charge of receiving the information and issuing the corresponding response; thus, if there is a lot of light, the pupil will become smaller than if we are in a dark room, for example.

The changes that occur within our body due to external conditions are known as “stimuli” and can be from light to other factors such as a blow, some noise, temperature, and so on. When our body reacts to this stimulus, we speak of a “response” that is transmitted from the nervous system to the brain, the key organ in this entire process.

The nervous system is divided into two systems, the central and the peripheral; both are connected with sensitive receptors, with muscles or with glands that allow the correct transport of the information that we are receiving from the outside. In this OneHowTo article we give you some guidelines so that you know how to take care of the nervous system.

In general terms, we can say that the nerve function It is distinguished into three major essential blocks:

• Sensitive function: it is what allows our body to react to stimuli that can come from both inside the body and outside.

• Integrative function: after the body receives the stimulus, the body makes a response making the decision of the behavior that should be followed next (such as, for example, enlarging the pupils to be able to see better in the case of being in a dark environment).

• Motor function: it is the response that our body makes in the event that muscles have to contract or produce glandular secretions, depending on the type of stimulus we have received.

But to know exactly what are nerves forThen we are going to list a series of behaviors or experiences that you live regularly and that you can do thanks to the correct functioning of your nervous system. For instance:

• The nerves control both the voluntary movements of your body (running, gesturing, etc.) but also all those involuntary that you don’t even pay attention (breathing, heartbeat, etc.)

• They also allow us act reflexively and, for example, remove the hand from a hot place or support the hands when we fall to the ground.

• The nervous system is also responsible for coordinate other systems bodily such as respiratory (which we have already discussed) but also others that are basic for the proper functioning of our body such as digestive, circulatory, etc.

• Thanks to our nerves we can live the outside world and integrate it into our own experience. They are in charge of our senses function properly and that our body reacts to these external impulses (smells, the taste of food, landscapes, etc.)

• The survival instinct We also have it thanks to the nervous system that controls both conscious and unconscious impulses, causing us to react in unimaginable ways in risky situations.

• Because it is the system that internalizes external stimuli, the nerves are also responsible for manage emotions and, therefore, when they cannot be managed correctly due to emotional charges, we usually say that someone “has lost their nerves.” At OneHowTo we give you some of the best home remedies for nerves.

• Similarly, the nervous system also allows us to develop our conscience and ask ourselves questions about who we are, where we are, etc.

As you can see, the nervous system is the one that relates the external world with the internal one and, for this reason, it is a complex system that is subdivided into many types of nerves depending on the use they make as well as the area in which they find each other. Next, in OneHowTo, we are going to discover the types of nerves that exist that are classified into different blocks.

1) Depending on where the information received is taken:

• Afferent nerves: they carry the stimuli we receive from the skin or other organs to the brain.

• Efferent nerves: they are just the opposite, that is, they transfer the impulse from the brain itself to the muscles or glands.

2) According to the origin of the nerves:

• Cranial: they are the impulses that are born in the area of ​​the brain or the bulb.

• Spinal: originate in the spinal cord.

3) According to its function in the body:

• Sensory nerves: they send information that is captured through the senses.

• Motor nerves: they are the ones that send the stimuli to the glands and muscles.

• Sensitive nerves: the excitations that are received externally are internalized by the nervous centers.
