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, hydro...

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 cir...

Histology or Hystology - Basics of Histology: Histology Meaning and Types

Image
According to Wikipedia - Histology is a branch of biology that studies the structure, vital activity, and development of tissues of living organisms. This is usually done by dissecting the tissue into thin layers and using a microtome. Unlike anatomy,  histology studies the structure of the body at the tissue level. or Histology is the science of the structure, development, and life of the tissues of animal organisms. Tissues are part of organs and are composed of cells and non-cellular structures. Therefore,  histology  includes cytology (the study of the cell), general  histology (the study of tissues), and private  histology (the study of the microscopic structure of organs). or 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: epithelial tissue, connective tissue, muscle tissue, and nerve tissue...
