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 spinal nerve anatomy and organisation, relate spinal nerves to dermatomes and plexuses, describe related conditions at a general level, and route clinical questions to professionals.

One of the paired mixed nerves that emerge from the spinal cord through the intervertebral foramina, in humans thirty-one pairs grouped as cervical, thoracic, lumbar, sacral and coccygeal nerves, each formed from dorsal sensory and ventral motor roots and supplying a dermatome and myotome; spinal nerves form plexuses such as the brachial and lumbosacral plexuses and are involved in conditions such as radiculopathy.

What it is for: Nerves emerging from the spinal cord.

It can be explain anatomy and organisation; relate to dermatomes and plexuses; describe conditions in general terms; route clinical questions.
