    Brachial Plexus Lesion
  80. Characterized by progressive andirreversible deterioration of upper anlower motor neurons, resulting in bothupper and lower motor signs.Degeneration within the corticospinaland corticobulbar tracts gives rise toupper motor weakness andhypertonia. The hardening of thetracts as the degenerated neurons arereplaced by gliosis explains the term“lateral sclerosis”.
