Definition

“Precerebral” have been changed to “extracranial” as the latter term is the one generally used in the literature. Arteries to the brain are divided into intracranial and extracranial. The carotid siphon is included in the “intracranial” part of the carotid artery as the major part of the carotid siphon is located distal to the dural passage of the artery.
