This document provides an overview of human anatomy. It begins by defining anatomy and its subdivisions. There are two main divisions: gross anatomy, which studies structures visible to the naked eye, and microscopic anatomy, which examines structures too small to be seen without magnification. Gross anatomy includes surface anatomy, regional anatomy, systematic anatomy, and clinical anatomy. Microscopic anatomy contains cytology, the study of cells, and histology, the study of tissues. The document concludes by outlining several fields that anatomy is applicable to, such as medicine, research, biomechanics, and forensics.
