The peripheral nervous system use Tramadol

One of the major problems of clinical neurology are diseases of the peripheral nervous system. They account for almost half of adult neurological disease. Until recently, there was a steady picture of neuritis and polyneuritis. Over the last decade made a major contribution to the study of the etiology and pathogenesis of diseases of the peripheral nervous system how many tramadol to get high. It should be noted the successful fight against infections (syphilis, tuberculosis, malaria, polio, diphtheria, etc.). Opened and successfully studied systemic connective tissue disease, there are certain achievements in the study of genetic diseases is actively conducted an analysis of common metabolic disorders that affect the nervous system. Vertebrogenic established the origin of the absolute majority of diseases of the peripheral nervous system. Rapidly evolving doctrine of tunnel syndrome. All this predetermined substantial reduction in the role of infections in lesions of the peripheral nervous system. We have become widespread terms neuropathy, radiculopathy, polyneuropathy, which are defined as disorders of the peripheral nervous system predominantly infectious etiology. Characterizing the level of destruction and emphasize the multifactorial etiology. This allowed for a fundamentally new way to put issues related to the treatment of these diseases.

By the peripheral nervous system include front and rear roots of the spinal cord, intervertebral spinal ganglia, spinal nerves, they plexus, peripheral nerves and roots and ganglia of the cranial nerves and cranial nerves.

Formation of peripheral nerve is as follows. The rear and front roots, drawing closer, to form a so-called intervertebral ganglion radicular nerve after ganglion, which is situated in the intervertebral foramen, must spinal nerve. Coming out of the intervertebral openings spinal nerves are divided into posterior branches that innervate the muscles and skin of the back surface of the back and neck, and more powerful front innervate the muscles and skin of the ventral trunk and extremities departments. Anterior branches of thoracic segments form the intercostal muscles; branches of cervical lumbar and sacral segments enter into definite connections, forming bundles of plexus: neck, shoulders, lumbar, sacral. From plexus beams extend peripheral nerve trunks, or peripheral nerves.

Peripheral nerves are mostly mixed and consists of motor fibers anterior roots (axons of the cells of the anterior horns), sensory fibers (dendrites intervertebral node cells) and vasomotor-secretory-trophic fibers (sympathetic and parasympathetic) from the respective cells of the gray matter of the side of the spinal cord horns and ganglia of the sympathetic trunk border.

Nerve fiber, part of the peripheral nerve consists of the axons located in the center of the fiber, the myelin sheath, or meat, dressed axons and Schwann sheath.

The myelin sheath of nerve fibers sometimes interrupted, forming a so-called traps Rainier. In the field of interceptions axial cylinder adjoins directly to the Schwann sheath. The myelin sheath provides the role of electrical insulator, it is supposed to participate in the processes of the axial cylinder exchange. Schwann cells have a common origin with nerve elements. They accompany the axons of peripheral nerve fibers in the same way as glial elements accompany the axons in the central nervous system, Schwann cells are therefore sometimes referred to as peripheral glia.

The connective tissue in the peripheral nerves presented shells, dress nerve trunk (epineurium), its individual beams (perineurium) and nerve fibers (endoneurium). The membranes are blood vessels that feed the nerve.
