pericardial cavity

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 human body.

Where the pericardial cavity 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 pericardial cavity connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. part of 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.

Questions

Where is the pericardial cavity?

What does the pericardial cavity connect to?

Part of: pericardial sac.

Is the pericardial cavity 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.
