heart tube in dogs

An epithelial tube that will give rise to the mature heart. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the heart tube is

An epithelial tube that will give rise to the mature heart. The atlas records it as a tissue at the tissue scale in the dog.

Where the heart tube 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 heart tube connects to

The atlas records 10 typed relationships for it, across 4 kinds of connection. part of embryo.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the heart tube. 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 heart tube, endocardial heart tube and endocardial tube. Searching any of those names reaches this page.
