chest in dogs

Subdivision of trunk proper, which is demarcated from the neck by the plane of the superior thoracic aperture and from the abdomen internally by the inferior surface of the diaphragm and externally by the costal margin and associated with the thoracic vertebral column and ribcage and from the back of the thorax by the external surface of the posterolateral part of the rib cage, the anterior surface of the thoracic vertebral column and the posterior axillary lines; together with the abdomen and the perineum, it constitutes the trunk proper[FMA]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the chest is

Subdivision of trunk proper, which is demarcated from the neck by the plane of the superior thoracic aperture and from the abdomen internally by the inferior surface of the diaphragm and externally by the costal margin and associated with the thoracic vertebral column and ribcage and from the back of the thorax by the external surface of the posterolateral part of the rib cage, the anterior surface of the thoracic vertebral column and the posterior axillary lines; together with the abdomen and the perineum, it constitutes the trunk proper[FMA]. The atlas records it as a region at the region scale in the dog.

Where the chest is

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

What the chest connects to

The atlas records 16 typed relationships for it, across 3 kinds of connection. part of thoracic segment of trunk and trunk.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the chest. 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 anterolateral part of thorax, front of thorax, pectus, ventral part of thoracic region, thoracic body wall and thorax. Searching any of those names reaches this page.

Questions

Where is the chest?

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

What does the chest connect to?

Part of: thoracic segment of trunk and trunk.

Is the chest 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.
