atrioventricular node in dogs

An area of conducting tissue between the atria and the ventricles of the heart that conducts the normal electrical impulse from the atria to the ventricles. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the atrioventricular node is

An area of conducting tissue between the atria and the ventricles of the heart that conducts the normal electrical impulse from the atria to the ventricles. The atlas records it as a tissue at the tissue scale in the dog.

Where the atrioventricular node is

It sits in the thorax and trunk, within the muscular and cardiovascular systems. 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 node connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of cardiac septum, conducting system of heart and interatrial septum.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the atrioventricular node. 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 nodal muscle tissue, AV node, Aschoff-Tawara node, atrioventricular nodal muscle tissue, node of Tawara and nodus atrioventricularis, and 4 more. Searching any of those names reaches this page.

Questions

Where is the atrioventricular node?

It sits in the thorax and trunk, within the muscular and cardiovascular systems. 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 node connect to?

Part of: cardiac septum, conducting system of heart and interatrial septum.

Is the atrioventricular node 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.
