optic stalk in dogs

The narrow, proximal portion of the optic vesicle which connects the embryonic eye and forebrain. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the optic stalk is

The narrow, proximal portion of the optic vesicle which connects the embryonic eye and forebrain. The atlas records it as a tissue at the tissue scale in the dog.

Where the optic stalk is

It sits 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 optic stalk connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of diencephalon and nervous system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the optic stalk. 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 stalks and pedunculus opticus. Searching any of those names reaches this page.

Questions

Where is the optic stalk?

It sits 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 optic stalk connect to?

Part of: diencephalon and nervous system.

Is the optic stalk the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
