用注射、固定透明的脑厚切片在立体解剖显微镜下观察了十一个新生儿大脑内微动脉的走行与配布。各大脑动脉在大脑表面反复分支,互相吻合,形成多角形和不规则形的软膜动脉网。各脑回内微动脉的走行和配布形象具有共同特征。皮质动脉由软膜动脉网发出,与脑表面垂直穿入大脑皮质,在皮质内是直行的,排列整齐,随沟回起伏。皮质长动脉管径为16～31微米,短的为7.5～15.4微米,形成多角形或不规则形的毛细血管网。髓质动脉从回顶穿入的完全直行,长的直达髓质深部,管径为48～61微米,短的只35～47微米。从脑沟穿入的髓质动脉在皮质内是直行的,至髓质则有不同程度的弯曲,随同纤维方向行走。髓质动脉的分支也都以直角分出,行一短程,又“T”形分叉,互相连接,构成近似长方格形的毛细血管网。中央动脉由脑底等处穿入,至纹状体的动脉在穿入脑实质以后,沿壳核浅层扇形分开,弧形上行;丘脑的动脉从后外、下内及上面各方面穿入,分支也均呈锐角,经3～4级分支后形成多角形,三角形、近圆形和不规则形毛细血管网。内囊的动脉多顺纤维方向行走,也直角分支,“T”形分叉,形成近似长方格形的毛细血管网,但杂有横行从豆状核至尾状核的分支。
The injection of fixed transparent brain thick slices in stereotactic microscope under the observation of 11 neonatal cerebral arteries and the distribution of micro-arteries. The cerebral arteries in the brain repeatedly branched surface, consistent with each other, the formation of polygonal and irregular soft membrane artery network. The intracranial arterioles have common features in their movement and distribution. Cortical arteries issued by the soft membrane network, and the brain surface penetrating the cerebral cortex perpendicular to the cortex is straight, arranged neatly, with ditch back and forth ups and downs. Cortical aortic diameter of 16 to 31 microns, 7.5 to 15.4 microns short, the formation of polygonal or irregular capillary network. Medullary arteries penetrate completely straight back from the top, long direct medulla deep, diameter 48 to 61 microns, only 35 to 47 microns short. The medullary arteries penetrating from the sulcus are straight in the cortex, while the medulla have different degrees of curvature, walking along with the fiber direction. Branches of medullary arteries are also separated at right angles, a short trip, and “T” -shaped bifurcation, connected to each other to form a network of approximately rectangular grid. The central artery penetrates into the brain floor, etc., and the artery to the striatum separates along the superficial hyphae of the putamen following the penetration into the brain parenchyma. The arteries of the thalamic brain penetrate into the posterior, inferior, and superior aspects , Branches also showed acute angle, after 3 to 4 branches to form a polygonal, triangular, nearly circular and irregular capillary network. Artery of the internal capsule to multi-fiber direction walking, but also right-angle branches, “T” -shaped bifurcation, the formation of approximately rectangular grid of capillary network, but miscellaneous rampant from lentiform to caudate nucleus branch.
