What are Some Common Histological Techniques Used to Study Animal Cells?

Some common histological techniques include fixation, embedding, sectioning, and staining. Fixation preserves the tissue's structure by using chemicals like formaldehyde. Embedding involves encasing the tissue in a medium like paraffin to facilitate sectioning. Sectioning involves cutting the tissue into thin slices using a microtome. Staining techniques, such as H&E, PAS (Periodic Acid-Schiff), and Silver Stain, enhance the contrast between different cell components, making them easier to study under a microscope.
