The elbow joint nerve, a small branch of the musculocutaneous nerve in the cat, was investigated with low power transmission electron microscopy. By taking a series of overlapping photographs a montage was constructed of the cross section appearance of the complete nerve. Thus, a complete count of the number and sizes of myelinated and unmyelinated fibres was obtained. Two peaks in the distribution of myelinated fibres were consistently found, one at 2-5 micrometers and the other at 8-11 micrometers. The number of unmyelinated fibres was much larger than the number of myelinated fibres, with an average ratio of 4.4:1. This proportion of unmyelinated fibres is higher than that found by earlier workers, but is comparable with that in other peripheral nerves.
猫的肘关节神经是肌皮神经的一个小分支，采用低倍透射电子显微镜进行了研究。通过拍摄一系列重叠照片，构建了完整神经横断面外观的拼接图。由此，获得了有髓纤维和无髓纤维的数量及大小的完整计数。有髓纤维的分布始终出现两个峰值，一个在2 - 5微米，另一个在8 - 11微米。无髓纤维的数量远多于有髓纤维，平均比例为4.4:1。无髓纤维的这一比例高于早期研究者的发现，但与其他周围神经中的比例相当。
