3 sheep of approximately 4 years of age were used in the experiments. In 2 sheep in the cervical part of trachea all the nervous branches reaching this organ were cut and the remaining sheep was control. The animals were alive for 21 days. The following material was sampled for investigations: medulla oblongata, cervical part of spinal cord, bilateral spinal ganglions from C1 to C8, bilateral nodus ganglion and zygomatic ganglion and left and right parts of the cervical vagus nerve. The material was fixed and cut into 15 micron sections and stained according to the modified method of Nissl. The experiments evoked vast regressive changes in the nervous cells of both central and peripheral nervous system which helped to determine the source of outlet of fibers innervating this organ. In this paper the sources of outlet for the parasympathetic nervous fibers were presented. It was found that parasympathetic nervous centers connected with trachea were located in 1/3 of the central part of nucleus parasympathicus, anterior to obex, so in this part of nucleus which is the main source of outlet for the esophageal dorsal trunk and the ventral vagus nerve.
实验使用了3只约4岁的绵羊。对2只绵羊，在气管颈部切断所有到达该器官的神经分支，其余1只绵羊作为对照。这些动物存活了21天。采集以下材料进行研究：延髓、脊髓颈部、C1至C8双侧脊神经节、双侧结节神经节和颧神经节以及颈迷走神经左右部分。将材料固定并切成15微米厚的切片，按照改良的尼氏法染色。实验引起中枢和外周神经系统神经细胞广泛的退行性变化，这有助于确定支配该器官的纤维的传出源。本文阐述了副交感神经纤维的传出源。发现与气管相连的副交感神经中枢位于迷走神经背核中央部分的前三分之一，在闩前方，即该核的这一部分是食管背干和迷走神经腹支的主要传出源。
