nerve root

A continuation of the neuron projection bundle component of a nerve inside, crossing or immediately outside the central nervous system. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the nerve root is

A continuation of the neuron projection bundle component of a nerve inside, crossing or immediately outside the central nervous system. The atlas records it as a nerve at the organ scale in the human body.

Where the nerve root is

It sits within the nervous system. Only the system is known. The position shown carries almost no spatial information.

What the nerve root connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. part of nervous system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the nerve root. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as initial segment of nerve and radix nervi. Searching any of those names reaches this page.

Questions

Where is the nerve root?

It sits within the nervous system. Only the system is known. The position shown carries almost no spatial information.

What does the nerve root connect to?

Part of: nervous system.

Is the nerve root the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
