mesoderm

The middle germ layer of the embryo, between the endoderm and ectoderm. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mesoderm is

The middle germ layer of the embryo, between the endoderm and ectoderm. The atlas records it as a tissue at the tissue scale in the human body.

Where the mesoderm 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 mesoderm connects to

The atlas records 17 typed relationships for it, across 4 kinds of connection. a kind of germ layer.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mesoderm. 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 mesoderm, entire mesoderm and mesodermal mantle. Searching any of those names reaches this page.

Questions

Where is the mesoderm?

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 mesoderm connect to?

A kind of: germ layer.

Is the mesoderm 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.
