cranial nerve

Cranial nerves are nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from segments of the spinal cord. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the cranial nerve is

Cranial nerves are nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from segments of the spinal cord. The atlas records it as a nerve at the organ scale in the human body.

Where the cranial nerve is

It sits in the head, within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the cranial nerve connects to

The atlas records 14 typed relationships for it, across 3 kinds of connection. part of head.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the cranial nerve. 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 cranial neural tree organ, cranial nerves and nervus cranialis. Searching any of those names reaches this page.

Questions

Where is the cranial nerve?

It sits in the head, within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the cranial nerve connect to?

Part of: head.

Is the cranial nerve 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.
