Research into course and variability of brain arteries in hare were performed on 38 adult hares of both sexes (males 23 and females 15). The arteries were filled with a synthetic latex at a constant pressure introduced with a medical syringe to the left ventricle. The source of blood supply to the brain was internal carotid arteries, whose branches formed an arterial circle of the brain, vertebral arteries, and basilar artery as the result of its anastomosis. Variability focused on a method of departure of middle cerebral arteries, which were multiple vessels in 39.5% of cases and rostral cerebellar arteries. Caudal communicating arteries in hare comprised bilateral anastomosis of internal carotid arteries and final branches of the basilar artery. It stabilized the steady flow of blood to all parts of the brain. Caudal cerebral arteries comprised final branches of the basilar artery. The largest capacity of all the arteries of the brain was observed in the main trunk of the basilar artery. The capacity of these vessels was 4.53 mm(3) on average. The factor of capacity of cerebral arteries in relation to weight of the brain reaches a high value in hare.
对38只成年雌雄野兔(雄性23只,雌性15只)的脑动脉走行及变异性进行了研究。通过医用注射器以恒定压力将合成乳胶注入左心室,使动脉充盈。脑的血液供应来源为颈内动脉,其分支形成脑动脉环,椎动脉以及由其吻合形成的基底动脉。变异性主要集中在大脑中动脉的发出方式,在39.5%的病例中大脑中动脉为多支血管,以及小脑前动脉。野兔的后交通动脉由颈内动脉的双侧吻合以及基底动脉的终支组成。它稳定了流向脑各部分的稳定血流。大脑后动脉由基底动脉的终支组成。在基底动脉主干中观察到脑所有动脉中最大的容量。这些血管的容量平均为4.53立方毫米。野兔脑动脉容量与脑重量的比值达到较高值。
