Tissue Fixation and Preparation Quiz

Tissue Fixation

• Slows down tissue metabolism and cellular activities
• Enhances tissue coloration for better visual inspection
• Facilitates the growth of microorganisms
• Preservation of tissue structure, prevention of decay, facilitating microscopic examination, preparation for molecular analysis and archiving

Good Fixative Characteristics

• Rapid tissue penetration, quick reaction, minimal structural alteration, safe to use, low cost
• Variable tissue penetration, variable reaction speed, moderate structural alterations, variable cost
• No tissue penetration, no reaction, no structural alteration, not applicable for use, no cost

Tissue Preparation - Dehydration

• To replace water in tissues with non-polar substances
• To increase the water content in tissues
• To preserve tissue structure
• To enhance tissue staining

This quiz evaluates your understanding of tissue fixation, its significance, and the characteristics of good fixatives. Additionally, it covers the process of tissue dehydration and its role in enhancing staining techniques. Test your knowledge on these essential concepts in histology.
