olfactory nerve

Nerve that carries information from the olfactory epithelium to the olfactory bulb[Butler and Hodos]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the olfactory nerve is

Nerve that carries information from the olfactory epithelium to the olfactory bulb[Butler and Hodos]. The atlas records it as a nerve at the organ scale in the human body.

Where the olfactory nerve is

It sits in the head, within the nervous system. Positioned deliberately as part of this species body plan.

What the olfactory nerve connects to

The atlas records 4 typed relationships for it, across 3 kinds of connection. a kind of anatomical structure and cranial nerve.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the olfactory 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 1n, first cranial nerve, nervus olfactorius [i], olfactory I, olfactory i nerve and olfactory nerve [I], and 8 more. Searching any of those names reaches this page.

Questions

Where is the olfactory nerve?

It sits in the head, within the nervous system. Positioned deliberately as part of this species body plan.

What does the olfactory nerve connect to?

A kind of: anatomical structure and cranial nerve.

Is the olfactory 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.
