Histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. [ 5 ] [ 6 ] It is an important part of anatomical pathology and surgical pathology , as accurate diagnosis of cancer and other diseases often requires histopathological examination of tissue samples. [ 10 ]
The most commonly used stain in histology is a combination of hematoxylin and eosin (often abbreviated H&E). Hematoxylin is used to stain nuclei blue, while eosin stains the cytoplasm and the extracellular connective tissue matrix of most cells pink. There are hundreds of various other techniques which have been used to selectively stain cells.
Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. [17] This contrasts with the methods of cytopathology, which uses free cells or tissue fragments.
It is also at this step that the pathologist selects areas that will be processed for histopathology. The eye can sometimes be aided with a magnifying glass or a stereo microscope, especially when examining parasitic organisms. Histopathology – the microscopic examination of stained tissue sections using histological techniques.
Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. [2] It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the histological structure of different parts of the gray matter in the cerebral hemispheres.
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
The cells comprising an epithelial layer are linked via semi-permeable, tight junctions; hence, this tissue provides a barrier between the external environment and the organ it covers. In addition to this protective function, epithelial tissue may also be specialized to function in secretion, excretion and absorption. Epithelial tissue helps to ...
[1] [2] The counterpart to gross anatomy is the field of histology, which studies microscopic anatomy. [ 1 ] [ 2 ] Gross anatomy of the human body or other animals seeks to understand the relationship between components of an organism in order to gain a greater appreciation of the roles of those components and their relationships in maintaining ...
