The aim of this study was to describe the arterial arrangement of the cervical spinal cord in rabbit because it has been used widely to examine the pathophysiology of spinal cord injury. The study was carried out on 20 adult New Zealand White rabbits. We prepared corrosion casts of the arterial system of the cervical spinal cord. Batson's corrosion casting kit no. 17 was used as a casting medium. The origin of the ventral spinal artery from the right vertebral artery was found on average in 40 % of cases. The origin from the left vertebral artery was found on average in 35 % of cases. The ventral spinal artery raised from the anastomosis of two ventral spinal arteries on average in 25 % of cases. The presence of spinal arteries entering the ventral spinal artery in the cervical region was observed in 46.2 % of cases on the right side and in 53.8 % of cases on the left side. On the dorsal surface we found two irregular dorsal spinal arteries receiving dorsal branches of spinal arteries or they were absent. Until the cervical spinal cord arterial arrangement in species of laboratory animals is described in detail, it will be very difficult to determine the appropriate species for experiments in this field. Variations in arterial arrangement can produce biased or erroneous results in studies.
本研究的目的是描述兔颈段脊髓的动脉分布情况，因为兔已被广泛用于研究脊髓损伤的病理生理学。本研究以20只成年新西兰白兔为实验对象。我们制备了兔颈段脊髓动脉系统的铸型标本。使用巴特森17号铸型材料套装作为铸型介质。腹侧脊髓动脉起源于右侧椎动脉的情况平均在40%的病例中出现。起源于左侧椎动脉的情况平均在35%的病例中出现。腹侧脊髓动脉平均在25%的病例中由两条腹侧脊髓动脉吻合形成。在颈段，右侧有46.2%的病例、左侧有53.8%的病例观察到有脊髓动脉汇入腹侧脊髓动脉。在背侧表面，我们发现两条不规则的背侧脊髓动脉，它们接受脊髓动脉的背侧分支，或者不存在这样的分支。在详细描述实验动物物种的颈段脊髓动脉分布之前，很难确定该领域实验的合适物种。动脉分布的差异可能会在研究中产生有偏差或错误的结果。
