fibrous pericardium

Membrane organ which is attached to the pericardial sac proper and the central tendon of diaphragm and is continuous with the pretracheal fascia.[FMA]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the fibrous pericardium is

Membrane organ which is attached to the pericardial sac proper and the central tendon of diaphragm and is continuous with the pretracheal fascia.[FMA]. The atlas records it as a organ at the organ scale in the human body.

Where the fibrous pericardium 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 fibrous pericardium connects to

The atlas records 8 typed relationships for it, across 5 kinds of connection. part of pericardium and thoracic segment of trunk.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the fibrous pericardium. 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 fibrous portion of pericardium and pericardium fibrosum. Searching any of those names reaches this page.

Questions

Where is the fibrous pericardium?

What does the fibrous pericardium connect to?

Part of: pericardium and thoracic segment of trunk.

Is the fibrous pericardium 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.
