Additive fixatives Study guides, Class notes & Summaries

Acetic Acid - correct answer Non coagulant, penetrates quickly and leaves tissues very soft. Used often as an additive to precipitate and preserve the nucleoproteins and fix the nuclei. Acetic Acid - correct answer Swells tissues dramatically by breaking collagen bonds and allowing bonds to absorb water. Used as additive to counter-act the shrinking effect of other fixatives. Formaldehyde - correct answer Non coagulant and additive fixative that reacts with amino groups that link pro...

Histopathologic Techniques: Fixation, Chapter 3 Part I (Gregorios)Fixation - correct answers the first and most critical step in histotechnology involves fixing and preserving fresh tissue for examination first aim: preserve cell (life-like) second aim: harden and protect tissues most important: stabilization of proteins Additive fixation and Non-additive fixation - correct answers the two basic mechanisms involved in fixation Additive fixation - correct answers the chemical constitue...

Histotechnology- Fixation Fixation: - 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 an...
