| 摘 要： | 用大体解剖及组织学方法研究了中国大鲵脊髓的形态结构及细胞构筑。其特点是:脊髓纵贯椎管全长;运动神经元分腹内侧群和背外侧群;中间神经元未分化成亚核;髓内感觉细胞尤存;白质中有散在的神经细胞。文中还就大鲵脊髓在进化历程中的位置作了讨论。

| Abstract: | The shape, structure and cytoarctitecture of the spinal cord in A.davidianus are studied by dissecting and histological methods.The following are considered to be the distinctive features of the spinal cord: It extends throughout the whole length of vertebral canal; Motoneurons can be divided into a dorsolateral and a venteromedial division. No subnueleus are formed by the interneuron; Inter medullary sensory cells can be seen; There are internuncial cells in the white matter. The evolutionary position of the spinal cord is also discussed. |
