RESUMO

The human body tissues change constantly, so the majority of them adapt to the new demand. The study objective is the morphological analysis of immobilized rats sciatic nerve. This is an experimental and longitudinal research which took 6 animals dividing them in GI and GC groups. Each group containing 3 animals. The immobilization kept the animals paw in extension for 15 days. The material analysis was done through an electronic microscope. The results presented fiber disintegration and appearance of axons clusters. In the frequency distribution occurred a 17% decrease in the major diameter band and a 16 % increase in the minor diameter band. Afterwards it is clear that an immobilization period is able to activate the neural plasticity generating morphological changes in the sciatic nerve fibers.
