Study Notes
Histopathology Overview
- Histopathology compares normal tissues against abnormal tissues to identify abnormalities.
- Abnormal tissues are examined in relation to other abnormal samples from the same area to find common features.
Importance of Proper Preparation
- Correct preparation of tissue samples is crucial to avoid misleading results.
- Tissues must be preserved in their original state post-removal from the body to maintain accuracy in analysis.
- Every handling stage in histopathological preparation needs to be reproducible to ensure consistent outcomes.
Challenges Post-Removal of Tissues
- Autolysis occurs after tissue removal or death, which is the self-digestion of tissues due to enzymatic activity.
- This natural process complicates the preservation and analysis of tissue specimens, emphasizing the need for immediate and proper fixation techniques.
