In cats with deefferented m. triceps, some stretch receptors of the dynamic type were shown to adapt rapidly after stretching of the muscle and keeping it at the new length, whereas other receptors revealed rapid and slow components of the adaptation. The units with different kinds of adaptation coexist in the same muscle, their afferents being related mainly to the group I, although overlapping with the group II afferents does exist. The above differences are revealed at high values of the muscle initial stretch. It seems that the adaptation slow component is based on a mechanical factor depending on the viscous-elastic properties of the tissue in the area of sensitive nerve terminals.
在三头肌去传入神经的猫中，一些动态型牵张感受器在肌肉拉伸并保持在新长度后显示出快速适应，而其他感受器则表现出适应的快速和缓慢成分。具有不同适应类型的单位共存于同一块肌肉中，它们的传入纤维主要与Ⅰ类相关，尽管与Ⅱ类传入纤维也存在重叠。上述差异在肌肉初始拉伸值较高时显现出来。适应的缓慢成分似乎基于一个机械因素，该因素取决于敏感神经末梢区域组织的粘弹性特性。
