Which of the following is NOT a branch of anatomy?

The term that is identified as not being a branch of anatomy is physiology. Anatomy primarily focuses on the structure and organization of living organisms, encompassing various subdivisions such as gross anatomy, which examines structures visible to the naked eye, microscopic anatomy, which involves the study of cells and tissues using a microscope, and regional anatomy, which looks at specific areas of the body and the relationships between the structures within those regions.

Physiology, on the other hand, pertains to the study of the functions and processes of the various systems, organs, and cells within the body. While it is closely related to anatomy and often studied together in fields like human biology and medicine, physiology is distinct because it deals with how the structures of the body work and interact, rather than their form and organization. Thus, it is categorized separately from the branches that focus solely on anatomy itself.
