Abstract

Associations between the axolemma of nodes of Ranvier and perinodal astrocytes in the amphibian and reptilian spinal cord were examined by electron microscopy. Our present results demonstrate the astrocytic processes at the nodes of Ranvier in the central nervous system of lower vertebrates. Such a presence in lower vertebrates is discussed in the framework of current views on neuron-glial interactions and their possible phylogenetic implications.

摘要

通过电子显微镜检查了两栖类和爬行类动物脊髓中朗飞氏结轴膜与结周星形胶质细胞之间的关联。我们目前的结果证明了在低等脊椎动物中枢神经系统的朗飞氏结处存在星形胶质细胞突起。在当前关于神经元-胶质细胞相互作用及其可能的系统发育影响的观点框架内，讨论了这种在低等脊椎动物中的存在情况。
