What is Histology?

Histology, also known as microscopic anatomy or microanatomy, is the branch of biology that studies the microscopic anatomy of biological tissues. It is the science of the microscopic structure of cells, tissues, and organs, allowing for the visualization of tissue structure and characteristic changes the tissue may undergo. Histology is commonly used in medical diagnosis, scientific study, autopsy, and forensic investigation. It involves the sectioning, staining, and examination of tissues and organs under a microscope, providing insights into the relationship between structure and function. The analysis of histopathological imagery, a related field, is essential for the study of disease using the microscopic examination of a biopsy or surgical specimen that is processed and fixed onto a slide. The detection of various components in histopathological imagery, such as cell nuclei, glands, and lymphocytes, can provide valuable information for the diagnosis and understanding of diseases. The study of histology and histopathological imagery is crucial in various medical and scientific contexts, contributing to the advancement of knowledge and the improvement of diagnostic capabilities.

“Histology is the study of the tissues of the body and how these tissues are arranged to constitute organs. This subject involves all aspects of tissue biology, with the focus on how cells’ structure and arrangement optimize functions specific to each organ.” – Mescher, 2021
