In two series of experiments on the anesthetized cats' receptors of m. triceps passive muscle spindles, the stretching was performed by flexing the foot in the 1st series whereas in the 2nd one the muscle was stretched by a cut tendon. The secondary endings revealed the 3 per cent maximum of the sharp-peak distribution of variation coefficients (VC) of interspike intervals within the limits of 1.2 to 12.0 per cent. The VC values of the primary endings discharges are distributed relatively regularly within the range of 3--14 per cent, the distribution limits being 2.5--18.0 per cent. The VCs of discharges of both receptor types are overlapping in low frequency of impulses succession. 18 per cent of primary terminals have the same discharge variability as the majority of secondary ones. In intact paw, discharges of over 25/sec frequency are rare, therefore the analysis was performed in respect to low frequencies. The terminals can be with caution identified by their discharge regularity.
在对麻醉猫肱三头肌被动肌梭感受器进行的两组实验中，在第一组实验中通过弯曲足部来进行拉伸，而在第二组实验中通过切断肌腱来拉伸肌肉。次级终末显示，峰间间隔变异系数（VC）的尖峰分布在1.2%至12.0%范围内，最大值为3%。初级终末放电的VC值在3%至14%范围内相对规则地分布，分布范围为2.5%至18.0%。两种感受器类型放电的VC值在冲动连续频率较低时重叠。18%的初级终末具有与大多数次级终末相同的放电变异性。在完整的爪子中，频率超过25次/秒的放电很少见，因此分析是针对低频进行的。可以根据放电规律谨慎地识别终末。
