The study of tissues is called histology. It is the study of the microscopic structures of animal and plant tissues. It involves examining a thin piece of tissue under an electron or light microscope. To distinguish the different tissue structures easily and accurately, certain staining techniques are often used.
Histology is an important tool of human medicine, veterinary medicine and biology. It is used in forensic investigations, autopsies, education and archeology. The people who practice histology are called histologists. The people who specialize in the study of human tissue structures are called pathologists.
Histopathology, which is the study of diseased tissues, is an aspect of histology since it applies histological techniques.
