The arterial supply of the human spinal cord was investigated in detail using microangiography and binocular microscopy after the specimens had been made transparent. (1) The arterial tributaries to the spinal cord were found to come from the anterior radicular arteries in a total number varying from 3 to 15, and from posterior radicular arteries numbering 14 to 25. The location of the great anterior radicular artery varied from Th8 to L3. This artery was most often the only ventral feeder to the lower cord. (2) The surface arteries of the spinal cord were mainly derived from the posterior longitudinal arteries with only tiny anastomoses from the anterior spinal artery. The pial artery plexus was best developed over the posterior surface of the cord, particularly at levels of the enlargements. (3) The intramedullary central part us supplied by the anterior spinal artery and a peripheral part mainly from the posterior longitudinal arteries. Anastomotic connections between the two systems or between individual arteries within the two systems could not be observed.
在将标本制成透明后，使用微血管造影术和双目显微镜对人类脊髓的动脉供应进行了详细研究。（1）发现脊髓的动脉分支来自前根动脉，总数为3至15支，后根动脉为14至25支。大前根动脉的位置从胸8到腰3不等。该动脉最常是脊髓下部唯一的腹侧供血动脉。（2）脊髓的表面动脉主要来自后纵动脉，与脊髓前动脉仅有微小的吻合。软膜动脉丛在脊髓后表面发育最好，尤其是在膨大水平。（3）脊髓髓内中央部分由脊髓前动脉供应，外周部分主要由后纵动脉供应。未观察到两个系统之间或两个系统内各动脉之间的吻合连接。
