| 摘要: |
| 将明胶墨汁溶液注入到15例狗脊髓动脉系统内,观察其灰质内动脉构筑,结果如下:供应脊髓灰质内的动脉分别自脊髓背外侧动脉、沟动脉和周缘支发出。背角内侧动脉和背角外侧动脉分布于背角的头和颈部。中间外侧动脉发出分支到灰质侧角。供应灰质腹角的动脉有腹角外侧、腹侧和内侧动脉。中间内侧动脉分布于灰质中间带的内侧2/3。背连合动脉供应背侧灰质连合。在中央管两侧各有一条中央管旁动脉,纵向将各沟连合动脉串连一起。分布于灰质内的相邻各动脉间均存在吻合,构成灰质内动脉网。 |

| Abstract: |
| The gelatin-ink solution was injected into the arterial system of the spinal cords in 15 dogs.The origin,distribution and the architectural patterns were examined.The arteries suppling gray matter of spinal cord in dog stem from the spinal dorsolateral artery,sulcus artery and the circum- marginal artery.The medial and lateral arteries of dorsal horn distribute in the head and neck of the dorsal horn.The intermedial lateral artery gives off branches to the lateral horn of the gray matter.The lateral, ventra... |
