cavity
(anatomy) a natural hollow or sinus within the body
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 anatomical cavities and their classification, describe embryonic cavities and their development, relay clinical relevance in general terms, and distinguish anatomical cavities from dental cavities and other senses.
In anatomy, a natural hollow or space within the body or an organ, such as the cranial, thoracic, abdominal and pelvic cavities, the oral and nasal cavities, and embryonic cavities such as the blastocoel, the fluid-filled space of the blastocyst, and the archenteron, the primitive gut of the gastrula; body cavities house and protect organs and are lined by membranes, and in dentistry the word also names a hole caused by tooth decay.
What it is for: Housing and protecting organs; spaces for development.
It can be explain kinds of body cavity; describe embryonic cavities; relay clinical relevance; distinguish senses.
Distinguishing features
Enclosed space
Lined by membranes
Houses organs
Developmental origins
What it looks like
Not a visible object from outside; spaces seen in anatomical sections and imaging.
How it is recognised
Natural hollow within the body
Body cavities, organ cavities, embryonic cavities
A dental cavity is decay; a cavity in physics or engineering is a different sense
Related models
is a kind of - a natural hollow

In practice
Families and kinds
dorsal cavities: cranial and spinal
ventral cavities: thoracic, abdominal and pelvic
organ and passage cavities: oral, nasal, tympanic, pleural, pericardial
embryonic cavities: blastocoel, archenteron, coelom
cavities in other animals, such as the body plans of invertebrates

What the second pass must settle

- How should anatomical ontologies be linked?
- The registry entry has merged aliases naming embryonic cavities; should they be split off?
