On the other hand, cytology is the study of cells of both animals and plants only. Identifies pathologies that affect health, either through pathogens (viruses and bacteria) as well as by body imbalances such as diabetes, high cholesterol, hemophilia, anemia, leukocytosis, etc. The term histology is derived from the Greek words histos and logos meaning 'web or tissue' and 'speak or account'. The specialist doctor who does the examination under the microscope is called a pathologist. Therefore, the microscope is the fundamental tool.

Those interested in pursuing a career as a histotechnician will take such classes at four-year colleges such as Tulane University, University of Minnesota-Twin Cities, University of California at Davis and University of Illinois at Urbana-Champaign. Therefore, histology studies the minimal structures that make up living organisms. Histology is the study of the cells and tissues of plants, animals and humans. In the 19th century, the recognition of the cell as essential unit of living beings (H. Dutrochet, JP Müller and PJ François Turpin) and as structural and functional unit of organisms (FT Schwann and M. Schleiden) was essential. Match. They cut and stain tissues, and then image them. A: The field of histology focuses on studying the tissues of living things at a microscopic level. Histology is the study of the cells and tissues of plants, animals and humans. It can be described as microscopic anatomy. At the same time, Robert Hooke would do the same and manage to identify the existence of cells for the first time. Human histology places a strong focus on how cells become tissues, which become organs, which become body systems. What is Histology. Histology is the study of the microscopic anatomy (microanatomy) of cells and tissues. Histology is the study of the structure and function of the microscopic anatomy of plants and animals.
