Microtome is used for sectioning paraffin-embedded tissues for electron microscopy.
False
Bright Field Microscopy is also known as Compound microscopy.
True
Staining is the process of preventing post-mortem changes in tissues.
False
The purpose of the slide cover in light microscopy is to flatten the specimen.
False
The purpose of the base in a light microscope is to carry the microscope around.
False
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.
