body cavity
Let an agent explain body cavities and their organisation, relay comparative anatomy and development from anatomical sources, describe clinical relevance in general terms, and distinguish true coeloms, pseudocoeloms, potential spaces and organ lumens.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain body cavities and their organisation, relay comparative anatomy and development from anatomical sources, describe clinical relevance in general terms, and distinguish true coeloms, pseudocoeloms, potential spaces and organ lumens.
A fluid-filled or potential space within an animal body that houses organs, in vertebrates including the dorsal body cavity containing the brain and spinal cord and the ventral cavity divided into thoracic and abdominopelvic cavities, together with smaller spaces such as the tympanic cavity of the middle ear, and in invertebrates the true coelom, the pseudocoelom of nematodes and the cystid of bryozoans; anatomists also describe virtual or potential spaces between membranes that open only when fluid accumulates.
What it is for: Not applicable; an anatomical space.
It can be explain organisation; relay comparative anatomy; describe clinical relevance; distinguish kinds of cavities.
Distinguishing features
Houses organs
Lined by membranes
Developmental origin
Comparative variety
What it looks like
Not a visible object; internal spaces shown in anatomical sections.
Physical character
human major cavities: dorsal and ventral list
ventral subdivisions: thoracic, abdominal, pelvic list
serous membranes: pleura, pericardium, peritoneum list
How it is recognised
Space within the body housing organs
Dorsal and ventral cavities, thoracic and abdominopelvic cavities, tympanic cavity, coelom, pseudocoelom, cystid, virtual spaces
Organ lumens are inside hollow organs; potential spaces are closed until fluid enters

- The registry entry has merged aliases naming many distinct spaces; should they be split off?
