[Connections between spinal ganglia in the pathogenesis of reflex-distant pain syndromes]

Using the complex of the neurohistological research methods the author studied spinal ganglia, spinal cord (37 dogs) following the removal of groups of the spinal ganglia in the cervical and thoracic sections. Widely spread distant receptor-reflex systems of the connections between spinal ganglia accompanied by dendrites and axones were revealed. The fibres of these systems pass in the Bechterew intermediate regions of the posterior columns of the spinal cord. The straight interneuronal connections between the cervical and lumbar spinal ganglia were found. On the basis of the obtained data the author conducted analysis of the mechanism of the occurrence of reflex-distant pain syndromes in patients with ganglio-radiculoneuralgia in degenerative diseases of the vertebral column. The reflex-distant syndrome occurs due to irritation of spinal ganglion neurons accomplishing distant ganglion connections.
