In 2 cats nerves of the spinal pia mater were studied by means of electron microscopy. These nerves possessed no perineurium. However, it has been observed that flat cells of the surrounding connective tissue can form an incomplete covering for small nerve bundles. In addition the perivascular nervous plexus of subarachnoid arteries of the brain stem, which were examined in 1 animal, also showed no perineural sheath. These results are discussed with those reported in the literature dealing with the perineurium of other peripheral nerves. The observations concerning the distribution and the composition of leptomeningeal nerves are in accordance with those obtained by light microscopic investigations.
通过电子显微镜对2只猫的脊髓软膜神经进行了研究。这些神经没有神经束膜。然而，已经观察到周围结缔组织的扁平细胞可以对小神经束形成不完全的覆盖。此外，在1只动物中检查的脑干蛛网膜下动脉的血管周围神经丛也没有显示神经鞘膜。将这些结果与关于其他周围神经神经束膜的文献报道进行了讨论。关于软脑膜神经分布和组成的观察结果与通过光学显微镜研究获得的结果一致。
