ophthalmic nerve

The sensory nerve subdivision of the trigeminal nerve that transmits sensory information from the orbit and its contents, the nasal cavity and the skin of the nose and forehead. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ophthalmic nerve is

The sensory nerve subdivision of the trigeminal nerve that transmits sensory information from the orbit and its contents, the nasal cavity and the skin of the nose and forehead. The atlas records it as a nerve at the organ scale in the human body.

Where the ophthalmic 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 ophthalmic nerve connects to

The atlas records 11 typed relationships for it, across 5 kinds of connection. part of head and trigeminal nerve.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the ophthalmic 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 nerve V, branch V1, first branch of fifth cranial nerve, first division of fifth cranial nerve, first division of trigeminal nerve, nervus ophthalmicus (V1) and nervus ophthalmicus (Va), and 20 more. Searching any of those names reaches this page.

Questions

Where is the ophthalmic 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 ophthalmic nerve connect to?

Part of: head and trigeminal nerve.

Is the ophthalmic 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.
