Anatomical terminology

The internal carotid artery is an artery in the neck which supplies the anterior and middle cerebral circulation.[1]

In human anatomy, the internal and external carotid arise from the common carotid artery, where it bifurcates at cervical vertebrae C3 or C4. The internal carotid artery supplies the brain, including the eyes,[2] while the external carotid nourishes other portions of the head, such as the face, scalp, skull, and meninges.

The arterial input to the eye is provided by several branches from the ophthalmic artery, which is derived from the internal carotid artery in most mammals.
