TheFoundational Model of Anatomy Ontology (FMA) is a referenceontology for the domain ofhuman anatomy.[1] It is a symbolic representation of the canonical, phenotypic structure of anorganism; a spatial-structural ontology of anatomical entities and relations which form the physical organization of an organism at all salient levels ofgranularity.
FMA is developed and maintained by the Structural Informatics Group at theUniversity of Washington.[2]
FMA ontology contains approximately 75,000 classes and over 120,000 terms, over 2.1 million relationship instances from over 168 relationship types.[3]
Specifically, the FMA is a domain ontology that represents a coherent body of explicit declarative knowledge about human anatomy.
