epicardium in dogs

A region of the serous membrane that forms the innermost layer of the pericardium and the outer surface of the heart. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the epicardium is

A region of the serous membrane that forms the innermost layer of the pericardium and the outer surface of the heart. The atlas records it as a tissue at the tissue scale in the dog.

Where the epicardium is

It sits in the thorax and trunk, within the cardiovascular system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the epicardium connects to

The atlas records 5 typed relationships for it, across 4 kinds of connection. part of heart and visceral serous pericardium.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the epicardium. 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 heart epicardium, visceral serous pericardium of heart, visceral serous pericardium proper and pericardium visceral mesothelium. Searching any of those names reaches this page.
