atrioventricular canal in dogs

The part of the heart connecting the atrium to the cardiac ventricle[ZFA]. In the developing heart, the constriction between the atrium and ventricle constitutes the atrial canal, and indicates the site of the future atrioventricular valves[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the atrioventricular canal is

The part of the heart connecting the atrium to the cardiac ventricle[ZFA]. In the developing heart, the constriction between the atrium and ventricle constitutes the atrial canal, and indicates the site of the future atrioventricular valves[WP]. The atlas records it as a region at the region scale in the dog.

Where the atrioventricular canal is

It sits in the thorax and trunk, within the cardiovascular system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the atrioventricular canal connects to

The atlas records 6 typed relationships for it, across 4 kinds of connection. part of heart.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the atrioventricular canal. 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 AV canal, AVC, atrial canal, atrio-ventricular canal, canalis atrioventricularis and ependymal canal. Searching any of those names reaches this page.

Questions

Where is the atrioventricular canal?

It sits in the thorax and trunk, within the cardiovascular system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the atrioventricular canal connect to?

Part of: heart.

Is the atrioventricular canal 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.
