intercostal muscle in dogs

The respiratory muscles that arise from the lower border of one rib and insert into the upper border of the adjoining rib. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the intercostal muscle is

The respiratory muscles that arise from the lower border of one rib and insert into the upper border of the adjoining rib. The atlas records it as a muscle at the organ scale in the dog.

Where the intercostal muscle is

It sits in the thorax and trunk, within the muscular system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the intercostal muscle connects to

The atlas records 8 typed relationships for it, across 5 kinds of connection. part of chest.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the intercostal muscle. 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 musculus intercostalis, intercostales, respiratory muscle and rib muscle. Searching any of those names reaches this page.
