Histology, also called microanatomy or microscopic anatomy is the study of tissues and cells. In histology, imaging techniques that are advanced are used to analyze and identify the cells and tissues present in an organism. Histology can be used to know the functions of cells and tissues, identify if there is any sign of disease in the cells and tissues of an organism and know the types of disease they are, and also to identify and verify unknown tissues to get the identity and specie of the organism.
How Histology is done
Electron microscopy which an example of light and specialized microscopy systems are used to view the prepared tissue samples for the tiny structures present inside them. The most common method of imaging technique used in histology is a simple to stain which is done by washing over cells by using highly specialized staining material. The formulated stain stick only to a particular part of the cell like the DNA. Only the DNA or any targeted part of the cell that is specially prepared for the imaging test stay stained after being washed away by water. This is to make viewing for other methods clearer and better.
Importance of Histology
Histology is important to:
- Compare with anatomical pathology.
- Predict what kind of illness an organism has because many disease start from the tissue level, e.g, cancer. That is; the diagnosis (to know what kind of disease an organism has, the prognosis (to the predict the nature of the disease of the organism), what type of treatments are available for effective use, and how effective the treatments are.
- give students insights and understanding of development and evolution.
