Body Space Body Space or Junction Body Junction quiddities
some quiddities: cavities inside joint Synovial cavity of vertebral arch joint junctions between cavities Esophagogastric Junction
some Body Spaces: Lumen of colon Ocular orbit Perichoroidal space Laryngeal cavity
some Body Spaces: Cavity of pulmonary alveolus Hepatic perisinusoidal space Interalveolar pore
some Junctions: Right neurocentral junction of eleventh thoracic vertebra Thoraco-abdominal junction Labial commissure of mouth

Junctions, Borders and Joints Junctions are boundaries between different anatomical structures(e.g. abdominopelvic junction) Borders delimit anatomical structures (e.g. inferior border of tympanic plate) Joints are systems (e.g. knee)
boundaries • bona-fide boundaries • fiat boundaries • (Smith and Varzi)
bona-fide boundaries “Inner boundaries involving spatial discontinuity (holes, fissures, slits) or qualitative heterogeneity (of material constitution, texture, electric charge) we shall call bona fide boundaries.” (Smith and Varzi)
bona-fide boundaries “The distinction between fiat and bona fide boundaries applies not only to inner boundaries but to outer boundaries, too. The surfaces of extended objects such as planets or tennis balls are of the bona fide sort.” (Smith and Varzi)
fiatboundaries “National borders, by contrast, as well as county- and property-lines and the borders of postal and electoral districts, provide examples of outer boundaries of the fiat sort, at least in those cases where they lie skew to any qualitative differentiations or spatial discontinuities (coastlines, rivers) in the underlying territory.” (Smith and Varzi)
junctions • bona-fide junctions • fiat junctions

is it a realist ontology? • objective reality representation • subjectivity taken into account anatomy diagnosis
