Abstract

Frog sciatic nerves show a continuing addition of new myelinated and nonmyelinated fibers with body growth. Along with increases in fiber number there are also marked changes in axon calibers and in the relative thickness of the myelin sheaths. Our data show that frog nerves, as opposed to mammalian nerves, are composed of fibers of different ages, stages of growth and stages of myelination.

摘要

青蛙坐骨神经会随着身体生长持续增加新的有髓鞘和无髓鞘纤维。随着纤维数量的增加，轴突管径和髓鞘相对厚度也会发生显著变化。我们的数据表明，与哺乳动物神经不同，青蛙神经由不同年龄、生长阶段和髓鞘形成阶段的纤维组成。
