摘要: Abstract The degeneration of axon terminals the lateral (cortico and rubrospinal) ventral (vestibulo- reticulospinal) descending propriospinal (lateral funiculus) systems was investigated by electron microscopy in cat spinal cord. We studied mean diameters terminals, their arrangement on neuronal structures grey matter, as well variety destructive changes synaptic terminals. average size ‘dark’ type degenerating fibers smaller than that ‘light’ medial systems. both funiculus differed from those funiculus. findings concerning sizes different correlate to a certain extent with electrophysiological data about nature action upon neurons.
