bundle of His in dogs

A part of the His-Purkinje system that transmits signals from the AV node to the cardiac Purkinje fibers[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the bundle of His is

A part of the His-Purkinje system that transmits signals from the AV node to the cardiac Purkinje fibers[GO]. The atlas records it as a tissue at the tissue scale in the dog.

Where the bundle of His 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 bundle of His connects to

The atlas records 10 typed relationships for it, across 6 kinds of connection. part of cardiac ventricle, conducting system of heart and myocardium of ventricle.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the bundle of His. 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 bundle, AVB, His bundle, atrio-ventricular bundle, atrioventricular bundle and atrioventricular bundle muscle tissue, and 4 more. Searching any of those names reaches this page.

Questions

Where is the bundle of His?

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 bundle of His connect to?

Part of: cardiac ventricle, conducting system of heart and myocardium of ventricle.

Is the bundle of His 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.
