Histotopography

Histotopography (from the Greek histos - tissue and topos - place) is a science that studies the patterns of distribution of tissue elements in the organs and tissues of the body. It is one of the main disciplines of histology - the science of the structure of tissues and organs of living organisms.

A histotopographic study allows us to establish which tissues and organs are located in a certain place in the body, what their number is and what functional significance they perform. This is especially important when diagnosing diseases, since pathological changes in tissues can lead to changes in their histotopography.

To study histotopography, various methods are used, such as microscopic examination, immunohistochemistry, electron microscopy and others. These methods can determine which cells are found in certain areas of tissue, their number, shape and size, as well as what proteins and other molecules are contained in the cells and tissues.

One of the most important aspects of histotopographic research is the study of cell distribution in tissues and organs. For example, in the lungs, epithelial cells are located on the surface of the alveoli, and in the liver, liver cells are located in lobules.

In addition, histotopographic examination can help in determining the location of tumors and other pathological processes in tissues. For example, breast cancer may be localized to a specific area of ​​the breast, which can help guide treatment decisions.

Thus, histotopographic science is an important tool for studying tissues and organs and for diagnosing and treating various diseases.

Histotomography (Greek-HISTO - tissue + TOPO-place + GRAPH + writing) - a technique for analyzing the structure (identifiable features of the submicroscopic structure of tissue.) of tissues and organs, a set of rules for describing the morphological structure. The most developed branch of histology, which allows one to describe in sufficient detail the patterns of distribution of organs among tissues and various tissues among organs, as well as morphometric parameters within organs. It necessarily uses morphometry - a method of counting the number of cells (cellularity), measuring their linear dimensions.
