Anatomy makes it possible to study both the structure and the arrangement of the organs of a living being, also analyzing how they are related. It is a broad science that requires subdivisions that allow for an adequate study to cover a correct analysis of the body.
Regional anatomy, also known as topographic, is one of the types of anatomy that allows the study of the human body by regions, analyzing each region separately and studying all the aspects that make it up. In this article, we explain the Definition of regional anatomy and its form of study in detail.

Regional anatomy definition
The regional or topographic anatomy allows the study of the human body by dividing it into large regions such as the upper and lower limbs, head, or chest. For this, different criteria are followed that allow the analysis of each region separately, studying all the structures that make it up and how they are related.
Cross-sectional anatomy and surface anatomy are types of regional anatomy.
