Responses of primary and secondary endings of muscle spindles were studied after tenotomy and hypertrophy in the cat soleus muscles. Under constant load (100 g) background activity of primary endings in a control muscle was 17 +/- 1.5 imp/s. It did not change in hypertrophic muscle and increased after tenotomy to 26 +/- 1.5 imp/s. Responses of secondary endings did not change under the same conditions. The frequency of a response from primary and secondary endings of tenotomized and hypertrophic muscles were higher during dynamic and static phase of stretching as compared to response of normal muscle spindles. Primary endings of tenotomized and hypertrophic muscles were able to repeat vibration up to 200 Hz, while secondary endings responded only with some increase in the discharge frequency.
在猫比目鱼肌进行肌腱切断术和肥大处理后，研究了肌梭初级和次级终末的反应。在恒定负荷（100克）下，对照肌肉中初级终末的背景活动为17±1.5次/秒。在肥大肌肉中该活动没有变化，而在肌腱切断术后增加到26±1.5次/秒。在相同条件下，次级终末的反应没有变化。与正常肌梭的反应相比，在拉伸的动态和静态阶段，肌腱切断和肥大肌肉的初级和次级终末的反应频率更高。肌腱切断和肥大肌肉的初级终末能够重复高达200赫兹的振动，而次级终末仅在放电频率上有一些增加。
