ganglion
Let an agent explain ganglia as nervous system structures, distinguish the anatomical sense from the ganglion cyst, relay anatomical terminology and functions from reference sources, and route clinical questions to clinicians.
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 ganglia as nervous system structures, distinguish the anatomical sense from the ganglion cyst, relay anatomical terminology and functions from reference sources, and route clinical questions to clinicians.
In anatomy, a cluster of nerve cell bodies outside the central nervous system, such as the dorsal root ganglia that carry sensory input and the autonomic ganglia that control organs, with basal ganglia as a related term for nuclei within the brain; the word also names a fluid-filled cyst near a joint or tendon, a separate sense.
What it is for: Relaying and processing nerve signals outside the central nervous system.
It can be explain the kinds of ganglia and their functions; distinguish the anatomical sense from the cyst; relay terminology and locations; route clinical questions.
Distinguishing features
Cell bodies outside the central nervous system
Sensory or autonomic function
Named by location
Homonym with the cyst
What it looks like
Not visible externally; a small swelling on a nerve containing cell bodies.
How it is recognised
Cluster of neuron cell bodies in the peripheral nervous system
Sensory, sympathetic and parasympathetic kinds
A ganglion cyst is a swelling near a joint, a different sense
Related models
is a kind of - a peripheral structure
is part of - its location
contains - cell bodies
is confused with - a joint swelling
In practice
Families and kinds
dorsal root and cranial nerve sensory ganglia
sympathetic chain and prevertebral ganglia
parasympathetic ganglia such as the pterygopalatine ganglion
enteric ganglia
basal ganglia as brain nuclei, a related usage
ganglia in invertebrate nervous systems

What the second pass must settle
- Should the ganglion cyst be a separate entry?
- How should anatomy ontologies be linked?
- The registry entry has merged aliases naming specific ganglia; should they be split off?
