Definite ultrastructural changes of the neuromuscular receptor organs were demonstrated in the young and adult rat masseter muscles either on the operated or unoperated side following the unilateral transection of the infraorbital nerve. The grade of the degeneration was intensive but quite similar in having no relation to the age of the rat when the operation was performed, while it increased drastically with time after the operation. On this base, it may be suggested that the sensory input coming from the various kinds of sensory receptors in the snout field do rather affect bilaterally the minor reflexive movements of the jaw. In other words, it can be said that the minor reflexive movements of the jaw might have been controlled by the sensory inputs coming from the snout sensory receptor organs. The definitely degenerated changes of the neuromuscular receptor organs in the masseter muscles should be regarded as disuse atrophy following the interception of the snout sensory input.
在成年和幼年大鼠的咬肌中，于眶下神经单侧横断术后，无论是手术侧还是未手术侧，神经肌肉感受器器官均出现了明确的超微结构变化。变性程度较为严重，但与手术时大鼠的年龄无关，极为相似，而在术后随时间急剧增加。基于此，可以认为来自吻部区域各种感觉感受器的感觉输入对下颌的双侧微小反射运动有显著影响。换句话说，可以说下颌的微小反射运动可能受来自吻部感觉感受器器官的感觉输入控制。咬肌中神经肌肉感受器器官明确的变性变化应被视为吻部感觉输入中断后的废用性萎缩。
