Question

What is the definition of Histology?

Answer 1

Hint: Histology is a branch of biology, which deals with the study of tissue’s microscopic structure. It is also known as microanatomy or microscopic anatomy. It is opposite to gross anatomy as anatomy is viewing structures without a microscope. It refers to the study of structures under a microscope, which can be infrared, electron or light.

Complete answer:
Histology is defined as the study of microscopic structure of plant or animal tissues.
Under histology, human tissue is also studied. This branch is called human histology. It is also defined as the scientific study of the microscopic structure of animal and plant tissues. It is an examination of the tissue's entire block. It is also the study of tissue organization. In histology, structures are not seen by naked eye, which is opposite to anatomy. Histology also involves the study of function and chemical composition of structures. Histology plays a crucial role in diagnosis and treatment of diseases since tissues are studied under microscope. Sectioning and staining are the important steps in histology before visualization under the microscope. The study is performed through tissue culture. Histological stains enhance the differential visualization of structures. Thus, histology is an indispensable tool in medicine and biology.
Histology is used in diagnosis of diseases. It is utilized to analyze the treatment effects. In autopsies, it is essential. It is exploited in forensic investigations to understand the reason of death. Cause of death can be found through histology.

Note:
Marie François Xavier Bichat is the father of descriptive anatomy and modern histology. Karl Mayer coined the term histology. Histology technicians are known to be specialized medical lab workers. They are also called as histotechnicians, medical scientists, histology technologists, biomedical scientists and medical laboratory technicians. Based on the observation, they provide diagnostic information.
