What is histology - histology definition

 

Histology is the science that studies the fine structure of the body and its related functions, and is a branch of anatomy in medical science. The so-called fine structure refers to a structure that can be clearly observed under a microscope. With the development of science and technology, the content of histology is constantly enriched, updated and developed.

 

Histology covers many areas, including medical histology, and organizational histology. Medical histology is the science that studies the fine structure of the body and its related functions. Medical histology mainly uses the microscope to observe the fine structure of the human body.

 

 

Medical histology

 

Behavioral histology (also known as organizational behavior) is a discipline that examines the influence of individuals, groups, and organizational structures on organizational behavior in an organization to improve the effectiveness of organizational management (this term is a disambiguation term, and focuses on medical Histology, and finally, more detailed histology of management behavior.

 

Histology is a morphological science that studies the relationship between organism's fine structure and its function. The main research object of medical histology is the human body. With the help of research on higher animals, it helps to explore and explain the knowledge gained from human body research.

 

The macroscopic study of the appearance and internal structure of organisms using knives, scissors, and other devices was anatomy, which began as early as the second century AD. After the invention of the microscope, the use of microscopes to study the fine structure of the organs of the organism, formerly called microanatomy, was part of the anatomy.

 

The word "tissue" in English comes from the French tissu. Its original meaning is woven. The term was first used in biology by French anatomist and physiologist Bichat (1771–1822). He believes that the membranes and organs that are separated by the naked eye are a variety of different properties and textures. He called these braids tissue (tissu) and proposed that the human body consists of more than 20 tissues, but he did not observe the microscope.

 

Later, the microanatomist Mayer (1829) coined the term histology. This word originated in Greek and consists of histos (organization) and logos (science), which means studying the organization's science. Since then, due to the improvement of the microscope, some scholars have made many observations on the microscopic structure of organisms, and they have summarized the human and higher animal tissues into four categories, namely epithelial tissue, connective tissue, muscle tissue, and nerve tissue. This view has been approved by many scholars. Still established.

 

 

These four types of tissues originate from the outer, middle, and endoderm stages of embryogenesis, and each has specific structural and functional characteristics, which are combined into various organs and systems according to certain distribution patterns. These organs and systems then form a complete organism. At first, "histology" was different from "microscopic anatomy." "Histology" focuses on the organization of the organism, and "microscopic anatomy" studies the fine structure of various organs.

 

Later, due to the progress of the research, it was considered that such division was unnecessary, and histology and microanatomy were collectively referred to as histology. The establishment and development of histology has enabled the complex micro-structure of the organism to be analyzed from the concept of the four types of tissues, so that the research on the microstructure of organisms has a basic guiding concept.
