It explains how different body structures work together in a particular region of the human body, such as the head or chest, and focuses on the diagnosis and treatment of disease or injury in the particular region that is being studied. In modern-day studies, the regional approach is used more commonly because it is easier to apply in a clinical setting than systemic anatomy/1%3A_Introduction_to_Anatomy_and_Physiology/1.1%3A_Overview_of_Anatomy_and_Physiology/1.1A%3A_Defining_Anatomy). The regional approach has many advantages, such as allowing students to focus on one region of the body at a time and thoroughly learn the muscles, nerves, vessels, etc. of the specific region. Regional anatomy also provides a better understanding of how a region functions as a unit by allowing us to explore the relationships of the various systems found there.
