Security mechanisms of the nervous system − Rakyat Biologi

By the tissue barrier mechanisms it should be added as a protective function of different brain membranes and nerves. Protection neuron and the surrounding glial processes and provide the Schwann cells, as well as the membrane of a neuron. The nervous system is protected as an immunological barrier.

The protective role played by special regulatory "balancing" (according to Pavlov) mechanisms aimed at prevention and elimination of emerging changes. In pathological conditions this principle is implemented in the activities of antisystems (GN Kryzhanovsky). The anti-activated or formed together to form a pathological system, limiting the development of the latter and inhibiting its activity. For example, if there is excessive pain activated antinociceptive system regulating pain sensitivity. Activation of antinociceptive system suppresses the occurrence of pain.

Antiepileptic system monitors the level of arousal in different parts of the central nervous system. Electrical stimulation of the caudal nucleus of the bridge related to antiepileptic system, suppresses the activity of epileptic foci in the cerebral cortex.

Tonic activity of anti-system is one of maintaining a sustainable health of mechanisms. Insufficient activity antisystems is a condition for the development of the pathological process. For example, the lack of antinociceptive system leads to increased pain sensitivity and the formation of painful syndromes; antiepileptic system failure causes a predisposition to seizures.
