用电子显微镜对正常和电刺激内脏神经后兔肾上腺髓质的神经末梢进行了观察。以每秒100次脉冲刺激10分钟，神经末梢的突触小泡数量增加。平均每平方微米囊泡数正常组为82 6个/平方微米，刺激组为132.7个/平方微米。在每秒400次脉冲的刺激下持续10分钟，突触小泡大量枯竭，神经末梢发生其他变化。平均囊泡数为29.2个/平方微米。这些结果被解释为在一种情况下末端的活动增加，而在另一种情况下作为突触连接的活动和疲劳的减弱。
The nerve endings of the adrenal medulla of the rabbit were studied under the electron microscope in the normal condition and after prolonged electrical stimulation of the splanchnic nerve. With a stimulus of 100 pulses per second for 10 minutes, there is an increase in the number of synaptic vesicles in the nerve ending. The mean number is of 82.6 vesicles per square micron in the normal and of 132.7 per square micron in the stimulated glands. With a stimulus of 400 pulses per second for 10 minutes, there is a considerable depletion of synaptic vesicles and other changes occur in the nerve endings. The mean number of vesicles is of 29.2 per square micron. These results are interpreted as indicative of an increased activity of the ending in one case, and as a diminished activity and fatigue of the synaptic junction in the other.
