Abstract

Large neurons at the ventrolateral edge of the snake's spinal cord are intimately associated with ligaments that closely adhere to the whole length of the spinal cord. Ultrastructural studies show close similarities of these cells and their processes with those of other mechanoreceptors. Furthermore, the ligaments undergo changes within the intervertebral areas that would enhance focusing the stimulus to the receptor area.

摘要

蛇脊髓腹外侧边缘的大型神经元与紧密附着于脊髓全长的韧带密切相关。超微结构研究表明，这些细胞及其突起与其他机械感受器的细胞及其突起极为相似。此外，韧带在椎间区域会发生变化，这将增强对感受器区域的刺激聚焦。
