The question of a possible sensory component in branches of the facial nerve innervating facial mimetic muscles in the cat was examined by the technique of retrograde axonal transport of horseradish peroxidase (HRP). HRP was applied to the proximal cut end of facial nerve branches innervating different facial muscle groups. Following survival periods of 71-75 h the animals were fixed by perfusion. Certain craniospinal sensory ganglia and the brain stem were processed histochemically for demonstration of HRP. HRP-labelled cell bodies, structurally resembling sensory neurons, were consistently observed ipsilaterally in the geniculate and proximal vagal ganglia and under certain conditions in the trigeminal ganglion. Measurements of HRP-labelled neurons in the geniculate and proximal vagal ganglia showed a wide size range but a unimodal size distribution with peaks in the small size range. These findings support the view that facial nerve branches innervating the mimetic muscles contain different types of sensory fibers.
通过辣根过氧化物酶（HRP）逆行轴突运输技术，研究了支配猫面部表情肌的面神经分支中是否存在可能的感觉成分这一问题。将HRP应用于支配不同面部肌肉群的面神经分支的近端切断端。在71 - 75小时的存活期后，通过灌注固定动物。对某些颅脊髓感觉神经节和脑干进行组织化学处理以显示HRP。在膝状神经节和迷走神经近端神经节同侧始终观察到结构上类似于感觉神经元的HRP标记细胞体，在某些情况下在三叉神经节中也能观察到。对膝状神经节和迷走神经近端神经节中HRP标记神经元的测量显示其大小范围很广，但大小分布呈单峰，在小尺寸范围内有峰值。这些发现支持了支配表情肌的面神经分支包含不同类型感觉纤维的观点。
