Histology is the microscopic study of tissues and organs achieved by staining, sectioning, and viewing those sections under a microscope ?. Histology is used in scientific study, medical diagnosis, autopsy, and even in the study of fossils ?.<\/p>\n\n\n\n
The four main human tissue types, epithelium, connective tissue, muscle tissue, and nervous tissue, can be viewed and distinguished with varying histological stains. There are a number of steps required before a slide can be viewed under the microscope.<\/p>\n\n\n\n
The fixation process preserves the structure of the tissue sample and prevents it from degradation by introducing chemicals that stimulate cross-linkage between proteins ?.<\/p>\n\n\n\n
Ethanol is added to achieve dehydration of a sample ?. After the tissue sample is dehydrated, xylene can be used to remove the ethanol.<\/p>\n\n\n\n
During this phase, the tissue samples are embedded in a solid material, which allows for thin sectioning in the next stage. Paraffin wax or plastic resin are often used at this stage.<\/p>\n\n\n\n
To section the specimen, it is placed on a precision cutting tool known as a microtome. The tissue is cut into sections of about 4-5 micrometers, which is the optimal thickness for staining.<\/p>\n\n\n\n
The appropriate stain is chosen based on its unique properties. For example, Hematoxylin and Eosin are combined in H&E staining. Cell nuclei are stained blue because Hematoxylin binds to DNA, which is acidic. The cytoplasm is stained pink because Eosin binds to proteins in the cytoplasm, which are basic.<\/p>\n\n\n\n
