Which term describes the study of structural changes in the body that occur as a result of disease?

• A. Pathological Anatomy
• B. Physiology or Physiological Anatomy
• C. Gross Anatomy or Macro-scopic Anatomy
• D. Microscopic Anatomy

Answer: (A)

The concept being tested is how terms denote changes caused by disease. Pathological anatomy describes the structural alterations in tissues and organs that arise from disease, focusing on what changes in form the disease produces. These disease-induced changes can be seen with the naked eye (gross pathology) or under the microscope (histopathology), but the unifying idea is that they are alterations produced by disease itself.

In contrast, physiology deals with how the body's systems function, not with structural changes. Gross anatomy and microscopic anatomy describe normal structures at different scales, not specifically the changes that occur because of disease. So the term that best captures the study of disease-related structural changes is pathological anatomy.
