This document defines anatomy and its branches. Anatomy is the study of the structure and organization of the body. The two main branches are gross anatomy, which studies macroscopic or visible structures, and microscopic anatomy, which studies microscopic tissues. Gross anatomy has regional and systematic sub-branches. Microscopic anatomy includes cytology, the study of cells, and histology, the study of tissues. Other branches discussed are embryology, surface anatomy, radiological anatomy, clinical anatomy, and methods for preserving cadavers.
