internal thoracic vein

A vessel that drains the chest wall and breats and arises from the superior epigastric vein, accompanies the internal thoracic artery along its course and terminates in the brachiocephalic vein. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the internal thoracic vein is

A vessel that drains the chest wall and breats and arises from the superior epigastric vein, accompanies the internal thoracic artery along its course and terminates in the brachiocephalic vein. The atlas records it as a vein at the organ scale in the human body.

Where the internal thoracic vein 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 internal thoracic vein connects to

The atlas records 8 typed relationships for it, across 4 kinds of connection. part of thoracic segment of trunk and trunk.

Supply and innervation

Venous drainage: musculo-phrenic vein and superior epigastric vein.

Also called

Also recorded as internal mammary vein and vena thoracica interna. Searching any of those names reaches this page.

Questions

Where is the internal thoracic vein?

What does the internal thoracic vein connect to?

Part of: thoracic segment of trunk and trunk.

Is the internal thoracic vein the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
