Nervous System is the most critical systems of the organism. Besides, it has multiple functions that bases on receiving and processing information from the environment.
Also, from inside the body to regulate the functioning of the other organs and systems.
So it can be done both by direct action and by supporting.
However, the endocrine system, through the regulation of the release of factors that stimulate the secretion of the different hormones.

The Function Of The Nervous System
It has the function of relation, since, as the word indicates.
So it relates the functions and stimuli of the different parts of the body through this central system.
Therefore in this way, humans and other animals may be able to coordinate their movements or responses, both consciously and reflexively.
Structure Of The Nervous System
To study it.
The human body has anatomically divided into two parts. So the central and the peripheral system of nerves.
The Central Nervous System
It comprises the part covered by a bone protection system formed by the skull and the vertebral canal of the vertebrae.
Also, it made up of the brain and the spinal cord.
The brain is one of the nerve centers that make up the brain.
In addition, it is located in the upper and anterior part of the cranial cavity and appears in all vertebrate beings.
The Brain Consists Of:
The medulla oblongata.
2)The Spinal Cord
The spinal cord connects to the brain and runs the length of the body inside the spinal column.
The Peripheral Nervous System
This encompasses all the nerves that leave the central nervous system to the entire body.
It made up of nerves and nerve ganglia grouped into.
Somatic Nervous System
It comprises three types of nerves which are the sensory nerves, the motor nerves, and the mixed nerves.
Vegetative Or Autonomic Nervous System
Vegetative includes the sympathetic and the parasympathetic nervous system.
Nervous System Concept Map
The following is a conceptual map showing the structure of it.
So the cells of our it is called neurons and are of utmost importance for their proper functioning.
In other words, they are responsible for transmitting sensory information.
Most importantly neurons are specialized cells that receive stimuli from all parts of our body and.
So in turn, command the responses for organs and other physical capacities to function correctly.
Information On Nervous System
This has a topographic distribution of information.
Indeed, well-defined nerve conduction pathways transmit each signal or message.
So some of them have relays or connections in various areas of the brain.
That is important to carry out higher mental functions in which association of information required as in learning.
The explain the association between phenomena.
The object with a potential injury or remembering even a painful event for an experience with such purposes a traumatic related situation.
System Of Nerves Diseases
It can suffer numerous diseases of different origins: infectious, hereditary, degenerative, cerebrovascular, Demyelinating, tumor.
Bacteria, viruses, or parasites can cause them.
Some of the most frequent are meningitis and brain abscess.
Huntington’s disease is among the inherited conditions that affect the functioning of the nervous system.
Parkinson’s disease and Alzheimer’s disease included in this group.
The involvement of the blood vessels that supply blood to the nervous system can cause severe damage to its structures. So this mechanism occurs in cerebral embolism and cerebral infarction.
When the myelin sheath is injured, nerve instincts slow or even stop.
Different types of cancer can affect the nerves primarily, including astrocytoma, oligodendroglioma, and meningioma.
