- 1What are fixatives?solutions that allow the preservation of cell and tissue structure after extraction
- 2What is a fixative navigation scenario?Fixative navigation measures are taken for through small large organs the fixatives are introduced via blood vessels during the fixation process fragmentation measures,
- 3Light Microscopy used what fixative?buffered isotonic solution of 37 percent formaldehyde
- 4Electron Microscopyglutaraldeyde
- 5What is the underlying mechanism behind tissue preservation that correspond directly to fixatives?set ability to react with amine groups of proteins which correspond directly to cultured human tissue
- 6Stainingmakes tissue components become distinguishable from one another
- 7What is special about stains that makes them able to pinpoint tissues structure?• The stain material that dyes are composed of fundamentally form electrostatic linkages with ionizable radicals of macromolecules that occupy tissues
- 8Basophilic dyes are broadly termed as what?Basic dyes
- 9Basic dyes (basophilic) correspond to what type of cell components?such as nucleic acids with a net negative charge(anionic entities)
- 10What is the basophilic spectrum?Tolvidine blue
Alcian blue
Methylene blue - 11Cationic components(positive charge) stain more readily with what dyesacidic dyes and are termed acidophilic
- 12Acid Dyes correspond to what cellular entitiesMitochonddria, secretory granules, and collagen
- 13The specific pathological entities that correspond to basic dyesDNA, RNA, etc
- 14MicrotomeAn instrument in which hardened block tissue is trimmed and placed for sectioning
- 15CryostatUsed for
Freezing tissues after they are sectioned - 16Freezing is used for what type of examinationRapid
- 17Fixation is fundamentally in terms of speed a what type of eaminationslower method
- 18Fixation and freezing both have what differenceshistochemical differences in terms of how they correspond to observation and analysis variables
- 19What does freezing not do that fixation doesinactivate enzymes that reside in the tissue structure
