1. Inspection: Inspect the slide using just your eyes and a good light source to first determine the shape of the prepared section. Occasionally, a specific section has a characteristic shape and is much easier to identify. e.g on the cross section of tracheal cartilage an annular preparation can be seen.
Is histology a biopsy?
For most biopsy specimens, this routine processing is all that’s needed. At this point (usually the day after the biopsy was done), the pathologist looks at the tissue under a microscope. Looking at the solid specimens in this way is called histology, which is the study of the structures of cells and tissues.
What is histology used for?
Often called microscopic anatomy and histochemistry, histology allows for the visualization of tissue structure and characteristic changes the tissue may have undergone. Because of this, it is utilized in medical diagnosis, scientific study, autopsy, and forensic investigation.
What are different methods of histology?
The process of histological staining takes five key stages, and they include fixation, processing, embedding, sectioning and staining.
Who named tissue?
Xavier Bichat
Xavier Bichat introduced word tissue into the study of anatomy by 1801. He was “the first to propose that tissue is a central element in human anatomy, and he considered organs as collections of often disparate tissues, rather than as entities in themselves”.

The four main types of stains used in histology are empirical, histochemical, enzyme histochemical and immunohistochemical.
Can a surgeon tell if a tumor is cancerous by looking at it?
Cancer is nearly always diagnosed by an expert who has looked at cell or tissue samples under a microscope. In some cases, tests done on the cells’ proteins, DNA, and RNA can help tell doctors if there’s cancer. These test results are very important when choosing the best treatment options.
