The elementary dynamic (ED) type receptors reveal a peculiar combination of high--frequency discharges in response to dynamic component of mechanical stimulus with fast disappearance of responses to static stretching of the muscle as well as post--activational discharges. 29 ED receptors were observed in stretching of isolated m. soleus, semi--isolated and intact m. triceps in anesthetized cats. Other 185 spindle afferents revealed stable static discharges. ED receptors constituted 5% of 570 units under study. When recording the responses of ED receptors to stretching and fisimotor stimulation, the muscle fiber and the afferent fiber were in a good functional condition. The property of fast adaptation of some primary endings of the muscle spindle seems to depend on connection of the afferent's sensitive terminals only with the nuclear--bag intrafusal fibers.
基本动态（ED）型感受器表现出一种特殊的组合：对机械刺激的动态成分产生高频放电，对肌肉静态拉伸的反应迅速消失，以及激活后放电。在麻醉猫的分离比目鱼肌、半分离和完整的肱三头肌拉伸过程中观察到29个ED感受器。另外185个肌梭传入纤维表现出稳定的静态放电。ED感受器占所研究的570个单位的5%。在记录ED感受器对拉伸和运动神经刺激的反应时，肌纤维和传入纤维功能良好。肌梭一些初级末梢的快速适应特性似乎仅取决于传入敏感末梢与核袋内肌纤维的连接。
