somite

Somites are spheres of epithelial cells that form sequentially along the anterior-posterior axis of the embryo through mesenchymal to epithelial transition of the presomitic mesoderm. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the somite is

Somites are spheres of epithelial cells that form sequentially along the anterior-posterior axis of the embryo through mesenchymal to epithelial transition of the presomitic mesoderm. The atlas records it as a tissue at the tissue scale in the human body.

Where the somite 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 somite connects to

The atlas records 6 typed relationships for it, across 2 kinds of connection. a kind of developing anatomical structure and epithelium.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the somite. 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 mesodermal cluster, epimere, epimere mesoderm, epithelial somite, somites and somitic mesoderm, and 1 more. Searching any of those names reaches this page.

Questions

Where is the somite?

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 somite connect to?

A kind of: developing anatomical structure and epithelium.

Is the somite 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.
