The sites of origin and termination of efferent and afferent fibers in the carotid sinus nerve (CSN) were investigated in the Japanese monkey. After application of a mixture of horseradish peroxidase (HRP) and wheat germ aggulutinin-conjugated HRP to the central cut end of the CSN, sensory ganglion neurons were labeled in the jugular ganglion of the vagus nerve, as well as in the superior and petrosal ganglia of the glossopharyngeal nerve. Many sympathetic ganglion neurons were also labeled retrogradely in the superior cervical ganglion. In the brain, many labeled terminals were seen ipsilaterally in the lateral division of the nucleus of the solitary tract (NST). A few neuronal cell bodies were also labeled ipsilaterally in a reticular region dorsomedial to the caudal one-third of the facial nucleus. The results indicate that the CSN of the Japanese monkey is composed mainly of afferent fibers terminating in the NST, that the afferent fibers in the CSN originate not only from the superior and petrosal ganglia of the glossopharyngeal nerve but also from the jugular ganglion of the vagus nerve, and that efferent fibers contained in the CSN arise from the medullary reticular formation and superior cervical ganglion.
在日本猕猴中研究了颈动脉窦神经(CSN)传出和传入纤维的起源和终止部位。将辣根过氧化物酶(HRP)和小麦胚芽凝集素结合的HRP混合物应用于CSN的中枢切断端后,迷走神经颈静脉神经节以及舌咽神经上神经节和岩神经节中的感觉神经节神经元被标记。许多交感神经节神经元也在颈上神经节中被逆行标记。在脑中,在孤束核(NST)外侧部同侧可见许多标记的终末。在面神经核尾侧三分之一背内侧的网状区域同侧也有一些神经元细胞体被标记。结果表明,日本猕猴的CSN主要由终止于NST的传入纤维组成,CSN中的传入纤维不仅起源于舌咽神经的上神经节和岩神经节,还起源于迷走神经的颈静脉神经节,并且CSN中包含的传出纤维起源于延髓网状结构和颈上神经节。
