The second method of histology processing is called frozen section processing. This is a highly technical scientific method performed by a trained histoscientist. In this method, the tissue is frozen and sliced thinly using a microtome mounted in a below-freezing refrigeration device called the cryostat. The thin frozen sections are mounted on ...
The Basic State Exam (Russian: Основной государственный экзамен; OGE) is the final exam for basic general education courses in Russia. It serves to assess the knowledge acquired by students over 9 years of schooling and is also used for admission to secondary vocational education institutions (colleges and ...
In the 19th century histology was an academic discipline in its own right. The French anatomist Xavier Bichat introduced the concept of tissue in anatomy in 1801, [23] and the term "histology" (German: Histologie), coined to denote the "study of tissues", first appeared in a book by Karl Meyer in 1819.
Animal tissues are grouped into four basic types: connective, muscle, nervous, and epithelial. [4] Collections of tissues joined in units to serve a common function compose organs. While most animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism.
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions.

Blood film stained with Giemsa showing Plasmodium (center of image), the parasite that causes malaria infections.. In 1891 Romanowsky [8] [9] [10] developed a stain using a mixture of eosin (typically eosin Y) and aged solutions of methylene blue that formed hues unattributable to the staining components alone: distinctive shades of purple in the chromatin of the cell nucleus and within ...
[10] [11] [1] When paired, this staining procedure is known as H&E staining, and is one of the most commonly used combinations in histology. [1] [12] [7] [14] Haematoxylin is also a component of the Papanicolaou stain (or PAP stain) which is widely used in the study of cytology specimens, notably in the PAP test used to detect cervical cancer ...
