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...

Absorption - correct answers When tissue is penetrated by, or absorbs, a dye solution and becomes colored without any other change or chemical reaction occurring. An example is the absorption of oil red O or Sudan black B by fat Achromatic - correct answers Without color, or not easily stained. In microscopy, achromatic lenses are corrected for two colors, red and blue. This helps produce images free of chromatic aberrations Acid mucosubstances - correct answers a term used to include bot...

Acetic Acid - 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 - 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 - Answer Non coagulant and additive fixative that reacts with amino groups that link protein chains together. ...
