external iliac vein in dogs
A large vein that connects the femoral vein to the common iliac vein. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins). Both external iliac veins are accompanied along their course by external iliac arteries. [WP,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the external iliac vein is
A large vein that connects the femoral vein to the common iliac vein. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins). Both external iliac veins are accompanied along their course by external iliac arteries. [WP,modified]. The atlas records it as a vein at the organ scale in the dog.
Where the external iliac vein is
It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.
What the external iliac vein connects to
The atlas records 5 typed relationships for it, across 3 kinds of connection. a kind of iliac vein.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the external iliac vein. 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.
