pericardial cavity in dogs

A potential space between the visceral and parietal layers of the pericardium. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pericardial cavity is

A potential space between the visceral and parietal layers of the pericardium. The atlas records it as a cavity at the organ scale in the dog.

Where the pericardial cavity is

It sits in the thorax and trunk, within the cardiovascular system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the pericardial cavity connects to

The atlas records 7 typed relationships for it, across 5 kinds of connection. part of organ and pericardial sac.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pericardial cavity. 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 cavity of pericardial sac, pericardial space and cavitas pericardiaca. Searching any of those names reaches this page.
