pyloric antrum in dogs

The area at the bottom of the stomach on the caudal side of the pyloric canal that contains gastrin-producing G cells, which stimulate acid production, and the luminal pH-sensitive population of somatostatin-producing D cells. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pyloric antrum is

The area at the bottom of the stomach on the caudal side of the pyloric canal that contains gastrin-producing G cells, which stimulate acid production, and the luminal pH-sensitive population of somatostatin-producing D cells. The atlas records it as a organ at the organ scale in the dog.

Where the pyloric antrum is

It sits 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 pyloric antrum connects to

The atlas records 5 typed relationships for it, across 4 kinds of connection. part of pylorus.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pyloric antrum. 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 antrum, antrum of stomach, stomach pyloric antrum, antrum of Willis, antrum pylori and antrum pyloricum, and 2 more. Searching any of those names reaches this page.

Is the pyloric antrum 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.
