The relationship between internodal length and external fibre diameter in the spinal cord was examined on glutaraldehyde perfused material from a number of cats. The relationship in all samples was highly significant and there was no significant difference either between animals or between the lateral and dorsal columns. However, there was considerable variability, some internodes being twice and others less than half as long as the length predicted by the regression equation. Our results showed that the relationship between internodal length and fibre diameter was essentially a linear function. No internodes shorter than 100 micrometers were seen.
在若干只猫的经戊二醛灌注的脊髓材料上，研究了脊髓节间长度与外部纤维直径之间的关系。所有样本中的这种关系都非常显著，并且在不同动物之间以及外侧柱和背侧柱之间均无显著差异。然而，存在相当大的变异性，一些节间长度是回归方程预测长度的两倍，而另一些则不到其一半。我们的结果表明，节间长度与纤维直径之间的关系本质上是一种线性函数。未观察到短于100微米的节间。
