ONTOLOGY COMPONENTS
Instances: The general purposes of an ontology is to provide a means of classifying individuals. , even if those individuals are not explicitly part of the ontology.
Classes: Abstract objects.
Attributes: Properties.
Relations: ways in which classes can be related to one another.
“The patella is a part of the knee and is a bone organ.”

Open questions and futur works
• FMA• Limited to anatomical structures• Genes expressions (phenotypes) • No used in practice (why?)
• MyCF• Focused on functions• Made to build physical 3D models • Take into account the finality of the models
