编辑同志: 编辑部转来王明阳医师的稿件,阅后颇受教益。在此,首先对王医师的指教表示深深的感谢和崇高的敬意,以下仅就此问题答复如下。 翻阅神经学和解剖学了解到,迷走神经在进化过程中,是由第4以下诸鳃神经所合成,其分布范围很广,尤左侧甚,它包括一般内脏传入,一般内脏传出、特殊内脏传出及特殊内脏传入诸种纤维,其内脏传入纤维起于结状神经节的假单极神经节细胞,其中一般内脏传入神经元的周围充分布于心脏、主动脉弓、呼吸器及消化器的粘膜,主要终止于一般内脏的感受器,中枢突入脑止于孤束核。而特殊内脏传入 Editorial comrades: The editorial department transferred to Dr. Wang Mingyang manuscripts, read after reading lessons. Here, first of all, I would like to express my deep appreciation and lofty respect to Dr. Wang for his advice. The following is the answer to the question below. Reading neurology and anatomy learned that the vagus nerve in the evolutionary process, is synthesized by the following 4 gill nerves, its distribution is very wide, especially left even very much, it includes general visceral afferent, general visceral came, special Visceral and special visceral afferent into the various fibers, the visceral afferent fibers from the nodose ganglion cells from the unipolar ganglion, in which visceral afferent neurons around the full distribution in the heart, aortic arch, respirators and Digestive mucosa, the main end of the general visceral receptors, the central protrusion into the brain at the solitary tract nucleus. The special internal organs introduced
