AbstractThe aim of this study was to describe the arterial arrangement of the cervical spinal cord in hare. The study was carried out on 20 adult European hares. Ten hares were used in the corrosion technique and ten hares in the dissection technique. After the killing, the vascular network was perfused with saline. Batson’s corrosion casting kit no. 17 © was used as a casting medium. After polymerisation of the medium, in ten hares the maceration was carried out in KOH solution, and in ten other hares formaldehyde was injected by the dissection technique into the vertebral canal. We found high variability in blood supply of the cervical spinal cord. The origin of the ventral spinal artery from the right vertebral artery was found on average in 65 % of the cases and from the anastomosis of two ventral spinal arteries was found on average in 35% of the cases. The presence of ventral branches of spinal branches entering the ventral spinal artery in the cervical region was observed in 37.9% of the cases on the right side and in 62.1% of the cases on the left side. The presence of dorsal branches of spinal branches was observed in 66.2% of the cases on the left side and in 33.8% of the cases on the right side.
