optic choroid

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 human body.

Where the optic choroid is

It sits in the head, within the cardiovascular and sensory systems. Positioned deliberately as part of this species body plan.

What the optic choroid connects to

The atlas records 12 typed relationships for it, across 6 kinds of connection. part of eyeball of camera-type eye, material anatomical entity 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.

Questions

Where is the optic choroid?

It sits in the head, within the cardiovascular and sensory systems. Positioned deliberately as part of this species body plan.

What does the optic choroid connect to?

Part of: eyeball of camera-type eye, material anatomical entity and uvea.

Is the optic choroid 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.
