lesser omentum in dogs

The double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the lesser omentum is

The double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum. [WP,unvetted]. The atlas records it as a organ at the organ scale in the dog.

Where the lesser omentum is

It sits in the abdomen and trunk, within the digestive system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the lesser omentum connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. part of organ, ventral mesogastrium and visceral peritoneum.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the lesser omentum. 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 gastrohepatic omentum, omentum minus and small omentum. Searching any of those names reaches this page.

Is the lesser omentum the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
