Histology - Function, Interaction, Method, and Components

Image
Histology (Greek histo - tissue + logos - research) is the science that studies the tissues of the body and how these tissues are located, forming organs. There are four main tissues known: e pithelial tissue, connective tissue, muscle tissue, and nerve tissue .  In Histology , Tissues are made up of cells and intercellular substance - two components that were previously considered independent of each other. The intercellular substance is formed by various types of molecules , some of them are highly organized and form complex structures such as collagen fibrils and basement membranes.   The main functions of Histology is   previously attributed to the extracellular substance included providing mechanical support for cells , transporting nutrients to cells , and removing catabolic products and secretory substances . It has now been established that, in addition to these functions, the components of the intercellular substance affect the cells that produce them.  In  Histology

It is incredibly difficult to attain human birth - the Means of achieving the highest human goal. If now I do not take advantage of this boon, when will it meet again?  - Shantideva See in the mirror, please. What do you see? This is the reflected light of your physical shell. You were able to get a human body not only thanks to your own efforts in past lives, but thanks to your parents, thanks to your mother. Once upon a time, upon learning about her pregnancy, she was immensely delighted, or maybe it was excitement or fear - what lies ahead now, how to cope with all those changes that are coming during pregnancy and after the birth of a child? Perhaps she had the support of her parents and her husband, or maybe it was a difficult period when she was all alone, and this decision depended only on her - the decision to be born to you or not. To get this chance to live life in a human body or stay in those areas where it is much more difficult to realize the possibility of accumulating e

Dystrophy - Pathology of Stromal Vascular Dystrophy

Image
Pathology of Stromal-Vascular Dystrophy  (mesenchymal, extracellular degenerations) develops as a result of metabolism disorder in the connective tissue and is identified in the stroma of organs and the vascular wall. Development of  Stromal   Vascular   Dystrophy  occurs in the gistion. Gistion is complex, which includes the microvasculature with the surrounding elements of connective tissue: ground substance, fibrous structures, and connective tissue cells. In the case of metabolism disorder, there is an accumulation of metabolism products, which are brought with the blood and lymph, or may be accumulated due to perverted synthesis, in the intercellular substance. Morphogenetic mechanisms of  Stromal Vascular Dystrophy  are such mechanisms as infiltration and perverted synthesis of substances. Causes of  Stromal Vascular Dystrophy  according to  pathology , are infectious and allergic diseases, rheumatic diseases, diseases of blood circulatory system, in particular, multiple myeloma;

Dystrophy - Pathology of Parenchymal, Hyaline-drop & Hydropic Dystrophy

Image
Parenchymatous dystrophies or Parenchymal Dystrophy (cell degenerations) is based on metabolism disorder and structural changes that occur in specialized cells of parenchymatous organs (liver, myocardium, kidneys). Besides, there is a metabolism disorder of membranous and cytoplasmic proteins, which leads to a change in  their physical and chemical characteristics. The trigger mechanism is the en zyme deficiency - enzymopathies. Table Of Contents Parenchymatous protein dystrophy (proteinosis) -  Parenchymatous protein dystrophy is morphologically characterized by  the appearance of protein granules in the cell cytoplasm. However, the appearance of protein granules may be of a physiological nature, as a manifestation of compensatory and adaptive reaction, without changing its physical and chemical  characteristics and be the result of the physiological activity of cells.  Parenchymatous protein dystrophy includes granular dystrophy, hya line-drop dystrophy, hydropic dystrophy, and kerat
