Various types of sensory stimuli may influence reflex laryngeal adduction. The reccurrent laryngeal nerve responses evoked by single shock and repetitive electrical stimulation of a number of sensory nerves have been neurophysiologically observed in twenty-five adult cats. Stimulation of major cranial afferents produces strong adductor responses. The magnitude of these evoked responses is approached only by stimulation of the splanchnic nerve in the abdomen. On the other hand, comparable stimulation of special sensory and spinal somatic sensory nerves produces rapidly attenuated evoked adductor responses. We postulate that while these latter adductor responses may be insuffcient to produce strong glottic closure, they may effectively modify phonatory function of the larynx. We have, therefore, attempted to demonstrate the effects of various sensory elicitations upon reflex laryngeal adduction as they may compositely influence both protective and phonatory control of this organ system.
多种类型的感觉刺激可能会影响喉内收反射。在25只成年猫身上，通过神经生理学方法观察了单次电击和对多条感觉神经进行重复电刺激所诱发的喉返神经反应。刺激主要的颅神经传入纤维会产生强烈的内收反应。只有刺激腹部的内脏神经才能达到这些诱发反应的强度。另一方面，对特殊感觉神经和脊髓躯体感觉神经进行类似刺激时，诱发的内收反应会迅速减弱。我们推测，虽然这些后者的内收反应可能不足以产生强烈的声门关闭，但它们可能有效地改变喉部的发声功能。因此，我们试图证明各种感觉刺激对喉内收反射的影响，因为它们可能综合影响该器官系统的保护和发声控制。
