photoreceptor layer of retina in dogs

The layer within the retina where the photoreceptor cell receptor segments reside. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the photoreceptor layer of retina is

The layer within the retina where the photoreceptor cell receptor segments reside. The atlas records it as a nerve at the organ scale in the dog.

Where the photoreceptor layer of retina is

It sits in the head, within the nervous 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 photoreceptor layer of retina connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. part of retinal neural layer.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the photoreceptor 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 retina photoreceptor layer, retinal photoreceptor layer, stratum segmentorum externorum et internorum (retina), stratum segmentorum externorum et internorum retinae, layer of rods and cones and retinal photoreceptor layers. Searching any of those names reaches this page.

Questions

Where is the photoreceptor layer of retina?

It sits in the head, within the nervous 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 photoreceptor layer of retina connect to?

Part of: retinal neural layer.

Is the photoreceptor layer of 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.
