pigmented layer of retina

A monolayer of pigmented epithelium covering the neural retina; develops from the outer of the two layers of the optic cup[ZFA]. the pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells, and is firmly attached to the underlying choroid and overlying retinal visual cells[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pigmented layer of retina is

A monolayer of pigmented epithelium covering the neural retina; develops from the outer of the two layers of the optic cup[ZFA]. the pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells, and is firmly attached to the underlying choroid and overlying retinal visual cells[WP]. The atlas records it as a tissue at the tissue scale in the human body.

Where the pigmented layer of 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 pigmented layer of retina connects to

The atlas records 10 typed relationships for it, across 3 kinds of connection. part of camera-type eye, organ and sensory system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pigmented layer of retina. 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 outer pigmented layer of retina, pigment epithelium of retina, pigmented retina epithelium, pigmented retinal epithelium, retinal pigment epithelium and retinal pigmented epithelium, and 10 more. Searching any of those names reaches this page.

Questions

Where is the pigmented layer of 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 pigmented layer of retina connect to?

Part of: camera-type eye, organ and sensory system.

Is the pigmented layer of retina 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.
