A <material anatomical entity> that is a single connected structure with inherent 3D shape generated by coordinated expression of the organism's own genome.
The formal definition for this definition does not include the influence of the environment on anatomical structure, as the class was reused from the Uber-anatomy ontology. This ontology defines anatomical structure for all organisms, including those whose anatomical structure might not be directly influenced by an interaction between genes and the environment. An example for this class serving as a mechanism of action would be in an intervention that targets change in anatomical structure. For instance, a gastric bypass surgery can change the structure of the stomach and intestines, and thereby change eating behaviours.
