oculomotor nerve

Cranial nerve which connects the midbrain to the extra-ocular and intra-ocular muscles. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the oculomotor nerve is

Cranial nerve which connects the midbrain to the extra-ocular and intra-ocular muscles. The atlas records it as a nerve at the organ scale in the human body.

Where the oculomotor nerve is

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

What the oculomotor nerve connects to

The atlas records 10 typed relationships for it, across 4 kinds of connection. a kind of cranial nerve.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the oculomotor 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

Questions

Where is the oculomotor nerve?

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

What does the oculomotor nerve connect to?

A kind of: cranial nerve.

Is the oculomotor 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.
