Abstract: We explore the morphological characteristics of the blood supply to the brain of Rhinopithecus roxelana, providing a basis for study of the morphology of the brain vasculature of the animal. We observed the origin and branches and distribution of the brain arteries of Rhinopithecus roxellana by arterial vascular casting and tissue transparance methods. Results showed the blood supplies to the brain in Rhinopithecus roxellana are basically as same as those to the human brain, and come from the internal carotid and vertebral artery. The above mentioned branches contribute to the formation of cerebral artery circle. The blood supply to the anterior cerebrum is mainly provided by the middle and anterior cerebral arteries which arise from the internal carotid. Basilar,cerebella and caudal cerebral arteries are formed by the vertebral artery,and
supply the brain stem,cerebellum and posterior cerebrum. But the brain of the Rhinopithecus roxelana does not have the anterior communicating artery.
