Anterior communicating Cerebral arterial circle Anterior cerebral Posterior Middle cerebral communicating Ophthalmic The brain receives its Posterior cerebral Basilar arterial supply from two Right internal carotid -Left internal pairs of vessels: carotid 1.vertebral artery 2.internal carotid artery Right common carotid Left vertebral Right vertebral Right subclavian Left subclavian Brachiocephalic Left common carotid Aortic arch
The brain receives its arterial supply from two pairs of vessels: 1. vertebral artery 2. internal carotid artery
Anterior communicating These two are interconnected in Cerebral arterial circle Anterior cerebral the cranial cavity to produce a Posterior Middle cerebral communicating cerebral arterial circle (of Willis), Ophthalmic which surrounds the hypophysial fossa(pituitary gland).

These two are interconnected in the cranial cavity to produce a cerebral arterial circle (of Willis), which surrounds the hypophysial fossa (pituitary gland)
