MICROSCOPIA E HISTOTÉCNICAS

Abstract

We see that histology studies the cells and the extracellular material that make up the tissues of the body, initially histology was limited by the limited capacity of the optical microscope, but over time electronic microscopes appeared that considerably expanded the field of study of histology. Therefore, this work intends to demonstrate the use of histological techniques for microscopic analysis. We can observe that the most used for this analysis is the optical microscope that leaves the structure of the sample more enlarged for better observation, for this process it is necessary to collect a sample of the tissue of such organism, which can be removed after the death of the “donor” which is called a necropsy, or during a biopsy. To avoid proliferation and prevent microorganism autolysis, preserving its real morphology, offering greater resistance for the next steps, then we perform cleavage, which consists of a process of reducing the dimensions of the fragments present in the collected sample. It is noteworthy that the microscopies in common use also include phase contrast microscopy, confocal microscopy, and transmission and scanning electron microscopy. identification, characterization, analysis and description of the structures of the numerous tissues and organs that make up the animal organism, also resulting in a diagnosis, through comparative studies of pathological and healthy tissues
