arch of aorta in dogs
The convex portion of the aorta between the ascending and descending parts of the aorta; branches from it include the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery; the brachiocephalic trunk further splits to form the right subclavian artery and the right common carotid artery. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the arch of aorta is
The convex portion of the aorta between the ascending and descending parts of the aorta; branches from it include the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery; the brachiocephalic trunk further splits to form the right subclavian artery and the right common carotid artery. The atlas records it as a organ at the organ scale in the dog.
Where the arch of aorta 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 arch of aorta connects to
The atlas records 11 typed relationships for it, across 5 kinds of connection. part of thoracic aorta.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the arch of aorta. 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
