Study Notes
Tissue Preparation Methods
- Living tissue examination often involves biopsy to obtain specimens.
- Preparation techniques can significantly influence the visibility and details of cellular structures.
Microvilli
- Microvilli are finger-like projections that enhance absorption by increasing the surface area of cells.
- Commonly found in the small intestine, contributing to nutrient uptake efficiency.
Histological Staining Techniques
- PAS (Periodic Acid-Schiff) staining is highlighted, which recognizes polysaccharides in tissues.
- Cationic and anionic properties are essential for specific staining procedures, aiding in differentiating tissue components.
Microscopy
- Condenser lenses focus light onto the specimen, essential for enhancing visibility of structures.
- Objective lenses enlarge and project the image of the specimen for detailed observation, vital in histological studies.
Examination Approaches
- Histology employs two main types of microscopy: light microscopy and electron microscopy.
- Light microscopy is often used for initial examinations, whereas electron microscopy provides higher resolution for intricate details.
