coronary sinus in dogs
The short trunk that recieves most of the cardiac veins carrying the blood from the myocardium and delivers it to the right atrium, with the sinoatrial connection occurring between the inferior vena cava and the atrioventricular orifice. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the coronary sinus is
The short trunk that recieves most of the cardiac veins carrying the blood from the myocardium and delivers it to the right atrium, with the sinoatrial connection occurring between the inferior vena cava and the atrioventricular orifice. The atlas records it as a organ at the organ scale in the dog.
Where the coronary sinus 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 coronary sinus connects to
The atlas records 7 typed relationships for it, across 3 kinds of connection. part of heart and venous system.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the coronary sinus. 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 sinus coronarius. Searching any of those names reaches this page.

Questions
Where is the coronary sinus?
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 coronary sinus connect to?
Part of: heart and venous system.
Is the coronary sinus 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.
