Vascularization of the brain in guinea pig. II. Regions of vascular supply and spatial topography of the arteries in particular parts of the brain

Abstract

It was shown that the parts of the brain in guinea pig are supplied through internal branches arising from the vertebral, basilar, and internal cartoid arteries. The medulla oblongata and pons receive branches originating from the anterior and posterior spinal arteries as well as from the inferior cerebellar arteries. The cerebellum reach rami arising from all cerebellar arteries. Mesencephalon is supplied by superior cerebellar, posterior cerebral, posterior communicating, and choroid arteries. The diencephalon receives branches from all three cerebral, posterior communicating, and choroid arteries. Telencephalon receives blood supply from three cerebral arteries as well as from posterior communicating and choroid vessels.
