optic foramen

An opening in the skull through which cranial nerve II passes.[MP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the optic foramen is

An opening in the skull through which cranial nerve II passes.[MP]. The atlas records it as a bone at the organ scale in the human body.

Where the optic foramen is

It sits in the head, within the skeletal 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 optic foramen connects to

The atlas records 7 typed relationships for it, across 3 kinds of connection. part of facial skeleton, material anatomical entity and orbitosphenoid.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the optic foramen. 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 optic canal, optic foramen, optic nerve (II) foramen, optic nerve foramen, canalis opticus and foramen opticum ossis sphenoidalis. Searching any of those names reaches this page.

Questions

Where is the optic foramen?

What does the optic foramen connect to?

Part of: facial skeleton, material anatomical entity and orbitosphenoid.

Is the optic foramen 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.
