floor plate in dogs

The specialized glial structure (non-neuronal cells) situated at the ventral midline of the embryonic neural tube; this structure spans the anteroposterior axis from the midbrain to the tail regions, separating the left and right basal plates of the developing neural tube, and serves as an organizer to ventralize tissues in the embryo as well as to guide neuronal positioning and differentiation along the dorsoventral axis of the neural tube. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the floor plate is

The specialized glial structure (non-neuronal cells) situated at the ventral midline of the embryonic neural tube; this structure spans the anteroposterior axis from the midbrain to the tail regions, separating the left and right basal plates of the developing neural tube, and serves as an organizer to ventralize tissues in the embryo as well as to guide neuronal positioning and differentiation along the dorsoventral axis of the neural tube. The atlas records it as a tissue at the tissue scale in the dog.

Where the floor plate is

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What the floor plate connects to

The atlas records 18 typed relationships for it, across 5 kinds of connection. part of neural tube.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the floor plate. 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 floorplate, FP, bodenplatte and ventral plate. Searching any of those names reaches this page.

Questions

Where is the floor plate?

This dataset records no region or system for it. No positional evidence of any kind. Drawn outside the body so it can still be found and counted, never inside it.

What does the floor plate connect to?

Part of: neural tube.

Is the floor plate 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.
