peritoneum

A serous membrane that lines the peritoneal cavity[VHOG,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the peritoneum is

A serous membrane that lines the peritoneal cavity[VHOG,modified]. The atlas records it as a tissue at the tissue scale in the human body.

Where the peritoneum is

It sits in the abdomen and trunk. Positioned deliberately as part of this species body plan.

What the peritoneum connects to

The atlas records 15 typed relationships for it, across 5 kinds of connection. part of abdominal wall and peritoneal sac.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the peritoneum. 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.

Questions

Where is the peritoneum?

It sits in the abdomen and trunk. Positioned deliberately as part of this species body plan.

What does the peritoneum connect to?

Part of: abdominal wall and peritoneal sac.

Is the peritoneum 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.
