Histología is the branch of biology that studies the microscopic anatomy of cells and tissues. It is concerned with the study of the structure of biological tissues, which are groups of cells that are similar in structure and function. Histologists use microscopes to examine stained tissue samples, called sections, to identify different cell types, their organization, and their relationship to other cells and structures. This field is fundamental to understanding organ function, disease processes, and the development of new medical treatments.

The study of histology involves preparing tissue samples for microscopic examination. This process typically includes fixation, which preserves the tissue structure; embedding, which provides support for thin sectioning; sectioning, which creates very thin slices of the tissue; and staining, which uses dyes to highlight different cellular components and make them visible under a microscope. Common stains like Hematoxylin and Eosin (H&E) are widely used to differentiate cell nuclei (blue) and cytoplasm (pink), respectively, revealing crucial details about cellular morphology.

Histology plays a vital role in various medical disciplines, including pathology, where it is essential for diagnosing diseases by examining abnormal tissues. It also contributes to research in developmental biology, understanding tissue regeneration, and developing drug therapies that target specific cellular mechanisms. The knowledge gained from histological studies forms the basis for much of our understanding of life at the cellular and tissue levels.
