What Is Internal Carotid

The internal carotid arteries are branches of the common carotid arteries that bifurcate into the internal and external carotids

Where is the internal carotid?

The internal carotid artery runs upward through the neck and enters the skull through the carotid canal, located in the petrous portion of the temporal bone just superior to the jugular fossa. Within the anterior portion of the canal, only thin bone separates the artery from the cochlea and the trigeminal ganglion.

What course is taken by the internal carotid artery?

The internal carotid then divides to form the anterior cerebral artery and middle cerebral artery. The internal carotid artery can receive blood flow via an important collateral pathway supplying the brain, the cerebral arterial circle, which is more commonly known as the Circle of Willis.
