cranial nervi
Let an agent explain the cranial nerves and their functions and pathways, describe clinical examination and common disorders in general terms, support learning in neuroanatomy, and route personal medical 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 the cranial nerves and their functions and pathways, describe clinical examination and common disorders in general terms, support learning in neuroanatomy, and route personal medical questions to clinicians.
The twelve pairs of nerves that emerge directly from the brain and brainstem rather than the spinal cord, numbered from the olfactory and optic nerves through the oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus and accessory nerves to the hypoglossal nerve, carrying sensory, motor and autonomic fibres to the head, neck and, through the vagus, the chest and abdomen; cranial nerves are examined clinically and their disorders indicate lesions in specific locations.
What it is for: Nerves emerging directly from the brain.
It can be explain functions and pathways; describe examination and disorders generally; support learning; route personal questions.
