Histotechnology- Fixation Question and answers already passed 2023/2024Fixation: - correct answers Alteration of biological tissue by chemical or physical means which stabilizes proteins found in tissue, preventing further metabolic activity. Purpose of Fixation: - correct answers To kill tissue and preserve it by limiting the effects of decay, putrefaction, and autolysis. Fixation also hardens tissue which makes it easier to gross, and easier to section once it is processed and embedded. Physical Agents: - correct answers - Heat and Desiccation possess fixative properties but they are not very practical and do not result in the high level of structural preservation that can be achieved by using chemical fixative agents. Chemical Fixatives: - correct answers -Are grouped by the way they interact with tissues they are used on. -they can either be additive or nonadditive and coagulants or noncoagulants Additive Fixatives definition and e
