Histological data is collected through a series of steps:
Tissue fixation: Preserving the tissue to prevent degradation. Embedding: Enclosing the tissue in a solid medium, usually paraffin wax, to facilitate sectioning. Sectioning: Cutting thin slices of the tissue for microscopic examination. Staining: Applying dyes to highlight different tissue components. Microscopic analysis: Examining the stained sections under a microscope.
