抄録

The purpose of this paper is to describe comparison of the human and rabbits spinal nerve roots. Rabbits have been selected in several spine studies as they are easier to obtain and keep. However, an appreciation of difference in structurel is essential for the correct extrapolation of results in the human stuation.<br>Six rabbits weighing 3.0-3.5kg. were used. Microangiography was done, and vascularity of their spinal cord and nerve roots were examined macroscopically, histologically and radiographycally.<br>The main results found in this study were as follows:<br>1) Segmental artery supplies 3 main spinal branches, i. e. radicular artery, spinal dorsal rami artery and spinal ventral rami artery. There are one anterior spinal artery and two posterior spinal arteries in spinal cord. Ventral radicular artery anasomoses to anterior spinal artery and dorsal radicular artery anastomoses to posterior spinal artery. These are essentially same in the human and rabbits.<br>2) The difference is the number of artery in spinal nerve roots. Rabbits have few arteries in their nerve roots. This suggests that nutrition of spinal nerve roots in rabbits depends on cerebrospinal fluid more than blood supply compared with the human.
