Collection can be done when the organism is still alive, through biopsy or during surgery; or even after death, during necropsy of animals or humans. This method consists of obtaining very thin sections of organ fragments, so thin that light can pass through them. When a tissue is removed from your body, it begins an autolysis process, so that this does not occur, we have the fixation process that interrupts this self-destruction, prevents the proliferation of micro-organism colonies and guarantees the quality of the tissue for further research.Acesso AbertoMATERIAIS HISTOLÓGICOSorganismonecropsiaCNPQ::CIENCIAS BIOLOGICAS::BIOLOGIA GERALRelatório de Pesquisa
