摘要
用血管铸型扫描电镜方法,对四只成年、健康恒河猴脑的尾状核内微血管的立体构筑进行了研究。尾状核内有三种动脉类型:①穿动脉;②长动脉;③短动脉。其静脉有二种类型:①深静脉;②浅静脉。同时还观察了尾状核内部的血管单位,这种血管单位是由一条位于中央的静脉和在周围的动脉组成。核内毛细血管不吻合成网眼。在观察中未发现毛细血管前动、静脉的吻合。
<ABSTRACT>The microangioarchitecture of the caudate nucleus in four healthy adult monkeys was studied by the replica method under the scanning electron micro-scope. The caudate nucleus arteries may be classified into three categories: ①perforative artery; ② long artery; ③ short artery, Veins classified into two categories; ① profound vein; ② superficial vein. The vascular unit in the caudate nucleus was also observed. The unit consisted of a centrally situatedand many peripherally situated arteries. The capillaries in the nucleus did not anastomose into meshes. The assumed precapillary arteriovenous anastemosis was not found.
