The trigeminovascular system, comprising the trigeminal subnucleus caudalis, the trigeminal nerve, and the dural meningeal arteries, is widely accepted as playing a fundamental role in the pathogenesis of migraine. That the dural arteries are involved in migraine has however never been proven and is based solely on animal studies and speculation. In this article, evidence is presented to show that the dura mater and its vasculature are not in any way involved in the pathogenesis of migraine and that the true vascular element of the trigeminovascular system is the extracranial terminal branches of the external carotid artery.
