Study Notes
Histology and Microscopy
Tissue Preparation
- A microtome is a device used to cut thin slices of tissue, typically 1-10 micrometers, for histological examination.
- Fixation is a process to preserve tissue structure and prevent decay, allowing for histological examination.
Microscopy Components
- The slide cover, also known as a coverslip, is a thin transparent plate that protects the specimen and allows for even sample illumination.
- The arm of a microscope is the vertical component that connects the microscope stage to the base, providing stability and support.
- The base of a light microscope provides a stable foundation, allowing for smooth and precise movement during observation.
