conduction block


con·duc·tion block

failure of impulse transmission at some point along a nerve fiber, although conduction along the segments proximal and distal to it are unaffected; clinically, most often the result of an area of focal demyelination or, less often, transient ischemia; when caused by focal trauma involving the periperal nervous system, called neurapraxia.
