ectoderm in dogs

Primary germ layer that is the outer of the embryo's three germ layers and gives rise to epidermis and neural tissue. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ectoderm is

Primary germ layer that is the outer of the embryo's three germ layers and gives rise to epidermis and neural tissue. The atlas records it as a tissue at the tissue scale in the dog.

Where the ectoderm 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 ectoderm connects to

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

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the ectoderm. 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 embryonic ectoderm. Searching any of those names reaches this page.

Questions

Where is the ectoderm?

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 ectoderm connect to?

Part of: pharyngeal membrane.

Is the ectoderm 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.
