internal carotid artery

A terminal branch of the left or right common carotid artery which supplies oxygenated blood to the brain and eyes[MP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the internal carotid artery is

A terminal branch of the left or right common carotid artery which supplies oxygenated blood to the brain and eyes[MP]. The atlas records it as a artery at the organ scale in the human body.

Where the internal carotid artery is

It sits in the head, within the cardiovascular system. Positioned deliberately as part of this species body plan.

What the internal carotid artery connects to

The atlas records 16 typed relationships for it, across 9 kinds of connection. part of blood vasculature, common carotid artery plus branches and head, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the internal carotid artery. 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 cranial carotid artery, internal carotid, ICA and arteria carotis interna. Searching any of those names reaches this page.

Questions

Where is the internal carotid artery?

It sits in the head, within the cardiovascular system. Positioned deliberately as part of this species body plan.

What does the internal carotid artery connect to?

Part of: blood vasculature, common carotid artery plus branches, head and vasculature of head.

Is the internal carotid artery 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.
