Study Notes

Histology

Fixation in histology preserves tissue architecture and prevents decay and autolysis.
A microtome is used for sectioning paraffin-embedded tissues, typically for light microscopy, not electron microscopy.
Staining in histology is a process that enhances contrast and visibility of tissue structures under a microscope.
In a light microscope, the base provides stability and support for the instrument.

Light Microscopy

Bright Field Microscopy is another term for Compound microscopy, which uses a compound lens system to magnify specimens.
The slide cover in light microscopy protects the objective lens from the specimen and prevents it from coming into contact with the slide.

Note: The incorrect statements in the original text are corrected and rewritten in the study notes to ensure accuracy and clarity.
