What is the granularity scope of the FMA?
The largest class represented in the FMA is the human body and the smallest anatomical class is biological molecule, which consists of two or more atoms held together by a covalent bond. The FMA represents anatomical entities from a very fine granularity such as the biological molecules to cells, tissues, organs, organ systems, major body parts, up to the entire body. It improves upon the currently available computable anatomical resources in both detail and scope of represented knowledge. The FMA contains anatomical classes and relationships necessary to model the structure of the entire human body.
