The existence of stretch receptors on the fasciae of masticatory muscles of the rat was demonstrated by means of methylene blue vital staining. A single cord of connective tissue on each side extends over the surfaces of the superficial masseter, temporal, and medial pterygoid muscles. The complex arborizations of unmyelinated nerve terminals originated from branches of the buccal nerve gathered closely within the cord forming the chain of stretch receptors. The chain was lengthened during the jaw closing phase, when the firing rates of stretch receptors probably increased. Results suggested that the chain of stretch receptors signaled position or movement of the mandible. The same stretch receptors were also detected on the masticatory muscles of some other rodents.
通过亚甲蓝活体染色法证实了大鼠咀嚼肌筋膜上存在牵张感受器。每侧一条结缔组织索延伸至咬肌浅层、颞肌和翼内肌表面。来自颊神经分支的无髓神经末梢的复杂分支紧密聚集在结缔组织索内，形成牵张感受器链。在下颌闭合阶段，该链会延长，此时牵张感受器的放电频率可能会增加。结果表明，牵张感受器链可传递下颌的位置或运动信息。在其他一些啮齿动物的咀嚼肌上也检测到了同样的牵张感受器。
