【摘要】 为了探讨川金丝猴脑动脉供应的形态学特征,为脑生物学研究提供结构基础,用血管铸型和组织透明方法追踪观察了川金丝猴幼体脑动脉的来源和分支分布。结果表明川金丝猴与人脑的动脉供应基本相同,也由颈内动脉和椎动脉供应。上述动脉的分支于垂体周围形成大脑动脉环。颈内动脉通过大脑前动脉和大脑中动脉主要供应大脑半球前部的血液,椎动脉参与形成基底动脉、小脑动脉系和大脑后动脉,供应脑干、小脑和大脑后部的血液。另外,川金丝猴幼体左、右大脑前动脉间缺少前交通动脉。更多还原

【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.更多还原
