PATHOLOGICAL SYSTEM


Pathological system - a new organization pathodynamic arising in the central nervous system in terms of damage, the activity of which is biologically negative (GN Kryzhanovsky). The main feature of the system is its pathological or maladaptive direct pathogenic significance for the organism. This feature distinguishes pathological from the physiological system, whose activity has an adaptive value and is aimed at achieving the desired result for the body.
In some cases, the pathologic system is the result of hyperactivity and out of control of the physiological system, in others - through the involvement of the central nervous system intact and damaged structures in a new, not pre-existing structural and functional organization.
The emergence of a pathological system represents the next stage of development of the pathological process. Formation and activity of pathological systems belong to the category of typical pathological processes realized in the system of relations level.
A good example of the pathological activity of the system is abnormal carding reflex. It occurs when you create a generator brachial department spinal apparatus carding reflex. Apparatus carding reflex becomes pathological determinant that turns carding physiological reflex in the pathological. The animal begins to comb the back paw reflex zone projection. These combing arise spontaneously. Over time, as the development of pathological system, they are becoming more frequent, persistent, and fierce, and may be terminated by lacerations of tissues. The animal is not able to stop the combing, despite their uselessness and harming effect. Such unrestrained violent behavior occurs in many forms of diseases of the nervous system in humans.
