Definition of Autonomic nervous system | What is Autonomic nervous system

Concept and Meaning of Autonomic nervous system

The nervous system is the network of tissues which takes care to capture and treat internal signals and external so that the body can develop an effective interaction with the environment. This system feels stimuli (sensory function), analyzes, keeps / stores information and encourage a decision to that effect (integration function), which translates into a muscular movement, a glandular secretion, etc. (motor function).
From anatomical point of view, you can divide the nervous system central nervous system or CNS (formed by the brain and the spinal cord) and peripheral nervous system or SNP (consisting of cranial nerves and the spinal/spinal nerves). From the functional point of view, on the other hand, it is possible to divide the system nervous autumn and the somatic nervous system.
The autonomic nervous system (or autonomic nervous system) receives information from the internal environment and sends a response to the muscles, glands and blood vessels. The functions of the nervous system are involuntary and are activated from the nerve centres located in the hypothalamus, brainstem and spinal cord.
What does the autonomic nervous system, is to transmit impulses from the central nervous system on the outskirts while stimulating the organs. The blood circulation, respiration, digestion and metabolism are some bodily functions regulated by the autonomic nervous system.
Autonomous nervous system functional division allows us to speak of the sympathetic system (consisting of paravertebral ganglia and lymph pre-aortiques or pre-vertebraux), the parasympathetic system (isolated ganglia) and the enteric nervous system (which controls the gastrointestinal system).
