What Exactly Does Histology Mean?

There are different methods and techniques for studying the human body. Histology is a branch of science that deals with the study of different tissues and the structures that they have. It is known to all that the structure of every single tissue in the human body is associated with the different functions that it has. Hence, histology has a very close relation with physiology as well as anatomy.

In a similar manner, histopathology can be defined as the study of different tissues that are commonly affected by the disease. This branch of science is pretty beneficial when it comes to making a particular diagnosis of any disease and determining the severity as well as the progress of a medical condition. In this article, students will learn histology meaning and the different studies related to histology. 

The Importance of Histology 

Histology is the study of the tissues as well as the structures that are associated with the tissues. This form of study proves to be really important when it comes to understanding the complexity of the tissue structure in the human body. When histology is combined with the science of pathology, it forms histopathology. 

This can be defined as the study of the tissues which are affected by some sort of disease. With the study of histopathology, experts are able to decide the type of the disease in the tissues as well as the progress that it has made. Not to mention that it also helps in the diagnosis of the diseases as well. For example, the histology of testis can be used to diagnose different diseases that can occur in the testicular region of the male reproductive system. 

Histology Meaning: What Does Histology Entail? 

Since there are different tests that are available for histology, there are a lot of skills that are required in order to perform these tests correctly. Hence, the laboratories and institutions tend to specialize in a specific type of tissue for the study. Here is a good example to clear the details. The histology of the ovary can be used to determine the severe issues which are found in the ovaries of a person. Also, a laboratory of neuropathology will put its main focus on the determination of diseases that tend to have an effect on the nervous system of the human body. 

Another one of the main uses of histology is in the field of biomedical research. This method of study can be used to determine the different causes as well as the treatment options for several diseases. This specific type of research method always takes place in a laboratory of a hospital. In a conventional sense, a histologist would use a microscope to look at the samples of the tissues in order to find out the underlying structures and conditions that are found in them. The studies of histology can be credited to the efforts of one person, Marie François Xavier Bichat who is also known as the father of histology.

Histology Techniques in Use: Staining 

Most of the cellular elements as well as the cells tend to have a transparent nature. Hence, it is pretty difficult to notice the difference between the cellular structure as well as the individual cells as a whole. Hence, the experts aren’t able to distinguish between the different cells and their structures even when the cells are seen through the microscope. This issue doesn’t allow them to study the cell structure. However, there is a very simple technique used in histology to make sure that this issue is prevented. The method of dyeing the samples with the help of a staining agent is pretty common in histological studies these days.

The histologists have actually come up with a new and different version of the staining technique that can be used in order to properly identify all the elements within the tissues when they are viewed through the microscope. This particular method is termed histochemistry. For example, in spleen histology, the staining dyes can be used in order to mark all the different types of individual cells of the spleen. This will in turn help the histologists in determining the structure of the cells in an easy and efficient manner. 

One of the most common forms of stains used in the process of histological studies is haematoxylin. This dye is completely blue in colour and can be used for diagnosing different tissue diseases in the best way. In some other methods, this dye is combined with another named eosin which is red in colour.


The term histology is used widely all over in order to denote the study of different tissues and the structures that they have. This article provides a detailed explanation of this particular branch of science. Students can use the information in the article to find out histology meaning and many such details.

FAQs on Histology

1. What is histology? 

According to the definition of the term, histology is the study of different tissues that are inside the human body as well as the structures of the tissues. It is a common fact that the structure of the tissues in a human body tends to be associated with the different functions that it has. Hence, the proper study of histology enables the researcher to find out more about the functions of different tissues. Apart from that, the combination of histology and pathology (histopathology) deals with the different tissues that are infected with diseases. With this branch of science, experts are able to figure out the diagnosis methods and treatment options for different tissue-related diseases. Marie François Xavier Bichat known as the father of histology.

2. What are the different histology techniques that are used today? 

It is seen that all of the elements that form the entire cellular structure of tissue are pretty transparent in nature. Hence, when these tissue samples are seen through the microscope, it becomes difficult to identify the structure that they have. This prevents the histologists from knowing what different tissues they are dealing with. However, there is a very simple procedure used in histology to eliminate such a problem. The use of staining dyes has become a revolutionary step in histology. There are certain dyes such as haematoxylin which is blue in colour and eosin which is red in colour. These dyes are combined together to stain the tissue samples which then makes it easier for the histologists to study the samples correctly.
