arteriole in dogs
The smallest division of the artery located between the muscular arteries and the capillaries[GO]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the arteriole is
The smallest division of the artery located between the muscular arteries and the capillaries[GO]. The atlas records it as a organ at the organ scale in the dog.
Where the arteriole is
It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.
What the arteriole connects to
The atlas records 14 typed relationships for it, across 6 kinds of connection. part of vasculature and thymus corticomedullary boundary.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the arteriole. 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 arteriola. Searching any of those names reaches this page.

Questions
Where is the arteriole?
It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.
What does the arteriole connect to?
Part of: vasculature and thymus corticomedullary boundary.
Is the arteriole 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.
