optic choroid in dogs

Vascular layer containing connective tissue, of the eye lying between the retina and the sclera. The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms the uveal tract[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the optic choroid is

Vascular layer containing connective tissue, of the eye lying between the retina and the sclera. The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms the uveal tract[WP]. The atlas records it as a region at the region scale in the dog.

Where the optic choroid is

It sits in the head, within the cardiovascular and sensory systems. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the optic choroid connects to

The atlas records 11 typed relationships for it, across 6 kinds of connection. part of chorioretinal region and uvea.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the optic choroid. 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 optic choroid?

It sits in the head, within the cardiovascular and sensory systems. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the optic choroid connect to?

Part of: chorioretinal region and uvea.

Is the optic choroid 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.
