External carotid - middle meningeal - Internal carotid - Extracranial - Skull base - Intrcranial - Carotid circulation - ophthalmic - posterior communicating - anterior communicating - middle cerebral The carotid artery begins in the base of the neck as the common carotid artery. About half way up the neck the common carotid branches into the Internal carotid and External carotid arteries. The neurosurgically significant branches of the external carotid artery are the: The middle meningeal artery enters the cranium through the foramen spinosum. It runs in the dura mater of the middle fossa that covers the temporal lobe. Tearing of the middle meningeal artery (most commonly by a fracture of the temporal bone of the skull) results in formation of an epidural hematoma. Extracranial
