HISTORY OF MICROSCOPE (Scroll down for more lectures)
The term "histology" (from the Greek "histos" - fabric and "logos" - word science) proposed a German scientist Robert Mayer in 1819, describing the science of tissue of multicellular animals and humans. However, the volume and value of the subject now histology went beyond a literal translation of his name. Histology studies not only tissue but also cells from which they are composed, the structure of organs and body systems. According to this there are sections of the subject:
-cytology (the study of cells);
-general histology, or actually histology (tissue studies);
-special histology (studying the structure of organs and systems).
-embryology, histology closely related to the science of embryo development , because the structure of the organism being studied in the course of their origin and development.
METHOD OF HISTOLOGICAL STUDIES
Most laboratory-histologist has to do with the production of fixed colored product. This is preceded by a large and troublesome work of doctors and laboratory personnel.The main stages of making histological preparation are:1-fence material, 2-fixing material, 3-washing 4-dewateringand compaction 5-percolation and sha ;6 - production cuts;7 - color and conclusion.
