A system it’s a ordered module of elements that interact with each other and are interrelated. The notion is used to name the set of concrete (material) objects and the set of abstract (symbolic) concepts endowed with organization.
Highly strung, on the other hand, is what belongs to or relative to nerves (the set of fibers that conduct impulses through various parts of the body).
These definitions allow us to refer to the nervous system, what is the tissue network which is responsible for capturing and processing signals for the body to develop an effective interaction with the environment.
The nervous system fulfills three great functions. The sensitive function is given by the ability to feel the stimuli (internal and external), while the integrating function is in charge of analyzing said stimuli, storing information and promoting a decision in this regard. The motor functionFinally, it is the response to stimuli through a muscular movement, a secretion of a gland, etc.
However, how could it be otherwise, in the correct functioning of the nervous system, the brain plays a fundamental role. And it is that this is in charge of processing the information it receives in what would be the cerebral cortex and, from there, collate it and later transform it into real material.
The neurons they constitute the only basic of the nervous system. These are specialized cells that coordinate actions through chemical and electrical signals that they send to the various regions of the body.
It is possible to divide the nervous system into Central Nervous System (CNS) Y peripheral nervous system (SNP). The CNS, formed by the brain and spinal cord, integrates sensitive information, generates thoughts and stores memory.
We would have to say that the brain is the mass that is contained within the brain and that it is surrounded by the meninges. It is about three membranes that, in turn, are composed of the pia mater, dura mater, and arachnoid mater.
Likewise, it should not be overlooked that the brain is divided into three clearly differentiated elements: the cerebellum, the brain, and the medulla oblongata. However, although these are the main and most voluminous, the midbrain or hypothalamus is also part of it.
The SNPFor its part, it is made up of cranial nerves (born in the brain) and spinal nerves (born in the spinal cord) and carries impulses.
In addition to all the above, we would have to emphasize that there are a series of diseases that have the peculiarity that they notably or exclusively affect the nervous system. Specifically, we would have to say that these are the most common or significant:
• Multiple sclerosis, which is a degenerative type of disease that causes serious damage to the central nervous system. It can cause from disability to a certain degree of reduced mobility.
• Parkinson’s. It is neurons that are directly affected by this disease, specifically those that are responsible for controlling muscle movements.
• Alzheimer’s. It is a degenerative pathology that causes damage to neurons and that results in notable memory losses.
