Histological section

A histological section is an image of a tissue or organ obtained by microtomy and staining with dyes. It is used in histology to study the morphology and function of cells and tissues at the microscopic level.

The preparation of a histological specimen begins with the collection of tissue or organ for examination. The tissue is then placed on a glass slide, which is covered with a thin layer of paraffin or other substance. After this, the glass surface is treated with a special solution to remove tissue debris and prepare for microtomy.

Microtomy is the process of cutting tissue into thin layers using a special tool - a microtome. The cut thickness is usually about 5-10 microns. After microtomy, a dye is applied to the surface of the glass to color the tissue.

Staining with dyes allows you to see the structure of the fabric and determine its functions. Depending on the purpose of the study, various dyes are used, such as hematoxylins, eosins, methylene blues and others.

After staining, the preparation is examined under a microscope. Thanks to the high resolution of the microscope, you can see the smallest details of tissue structure and detect changes associated with various diseases.

Histological preparation is an important tool in the diagnosis of diseases. Its use makes it possible to determine the presence and location of tumors, infections, inflammatory processes and other pathologies.

Thus, a histological section is an important tool for studying the structure and function of tissues and organs at the microscopic level, which makes it possible to diagnose various diseases and develop effective treatment methods.

A histological section is a special type of histology that is used to study tissues and cells of the body. It is produced by cutting the material lengthwise in a specific direction, usually perpendicular to the thickness of the fabric. The section allows you to study the internal structure of tissues and evaluate their functionality.

Most often, histological sections are used to analyze the morphology and structure of organs and tissues, as well as to diagnose various diseases. This method has a wide range of applications in medicine and biology, allowing one to obtain a detailed image of the tissue structure in different layers. Thanks to this, it is possible to determine the location of tumors, identify inflammatory or necrosis cells, analyze the anatomical structure of the organ, and much more.

During the production of histological preparations, many processes take place that require highly qualified specialists. Most materials need to be prepared in advance: take the tissue from the patient, thoroughly degrease and clean it, fill it with a fixing solution and place it in the oven. These processes are carried out by qualified specialists in the laboratory where the drug is prepared. The next step is to thinly cut the material using a special tool, increasing the quality and clarity of the image. The cutting process is not completed here: after obtaining the sections, they are fixed in formalin or
