Spleen - size, structure and shape, topographic anatomy, Function, Blood vessels, Nerves, and innervation Spleen. The size of the spleen. The structure of the spleen. Spleen shape The spleen, lien (Greek splen), is a richly vascularized lymphoid organ. In the spleen, the circulatory system is closely related to the lymphoid tissue, due to which the blood here is enriched with a fresh supply of leukocytes developing in the spleen. In addition, the blood passing through the spleen is released due to the phagocytic activity of spleen macrophages from obsolete red blood cells ("graveyard" of erythrocytes) and from pathogenic microbes, suspended foreign particles that have entered the bloodstream, etc. The size of the spleen, due to the richness of the vessels, can vary quite significantly in the same individual, depending on the greater or lesser filling of the vessels with blood. On average, the spleen is 12 cm long, 8 cm wide, 3-4 cm thick, and weighs about 170 g (100-200 g). D...

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...

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...
