Histology studies cells and tissues in plants, animals, and humans. It analyzes fabric composition, structure, and function, and studies disease and abnormalities. Histotechnologists take courses in cell biology and perform histological staining. Histology is similar to cytology and can be divided into three subclasses. It focuses on understanding cells, tissues, and organs.
Histology is the study of the cells and tissues of plants, animals and humans. It is a Greek word that derives from histos, which means fabric, and logia, which means knowledge. Together, the words combine to mean the analysis of fabric composition, structure and function. The discipline also studies cells and, to a lesser extent, organs.
Cells and tissue are placed under a microscope and studied closely for disease and other abnormalities. Science is built on the premises of larger disciplines because it studies the building blocks of a human, animal or plant structure. Tissues, which are collections of cells, are studied in groups. In plants, cell histology studies how cells process nutrients, eliminate waste, and interact with other cells. Human histology places a strong focus on how cells become tissues, which become organs, which become body systems.
Histology studies and programs are similar to cell biology courses. Those interested in pursuing a career as a hystotechnologist will take such courses at four-year colleges such as Tulane University, University of Minnesota-Twin Cities, University of California at Davis, and the University of Illinois at Urbana-Champaign. Topics covered in these courses include cell parts, cell junctions, tissue types and structures, connective tissue, and functions of the circulatory system. Both theoretical and practical learning takes place in these programmes, and individual or group laboratory projects are often assigned, with laboratory problems, reports and independent research. Students interested in histology should have a good understanding of subjects such as mathematics, biology and chemistry.
After a student completes the necessary courses and training, he or she becomes a histotechnologist or histology technician. These doctors perform histological staining, which involves placing a slice of tissue under a microscope and studying it. Histologists also study tissue structures and perform experiments. Histologists are similar to scientific technicians and biological, medical, agricultural and food scientists and may work with these medical personnel as well.
This field is often referred to as microscopic anatomy due to its reliance on carefully magnified studies. Furthermore, it is close to cytology, a branch of biology that deals exclusively with cells. This science can be divided into three subclassifications: cytology, histology proper (tissues), and organology. Not only does histology attempt to identify disease, the discipline focuses on understanding all things cells and tissues and, by default, organs.
