retina in dogs
The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the retina is
The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates. The atlas records it as a tissue at the tissue scale in the dog.
Where the retina is
It sits in the head, within the nervous and sensory systems. 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 retina connects to
The atlas records 25 typed relationships for it, across 10 kinds of connection. part of chorioretinal region, eye and nervous system, and 3 more.
Supply and innervation
Arterial supply: central retinal artery. Venous drainage: central retinal vein. Innervation: cranial nerve II and optic tract.
Also called
Also recorded as inner layer of eyeball, retina of camera-type eye, tunica interna of eyeball, Netzhaut and retinas. Searching any of those names reaches this page.

Questions
Where is the retina?
It sits in the head, within the nervous and sensory systems. 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 retina connect to?
Part of: chorioretinal region, eye, nervous system, organ, posterior segment of eyeball and camera-type eye.
Is the retina 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.
