Abstract

Prevertebral ganglia of cats and rats were studied by means of electron microscopy. Ganglia from control unoperated animals were compared with others following experimental interruptions of postganglionic and preganglionic afferent pathways. Elaborate interconnections were found between peripheral ganglia and visceral organs forming peripherally closed neuronal circuits. Three types of axons were distinguished as main constituents. On this morphological basis the existence of two kinds of peripheral reflex arcs has been postulated.

摘要

通过电子显微镜对猫和大鼠的椎前神经节进行了研究。将未手术的对照动物的神经节与节后和节前传入通路实验性中断后的神经节进行了比较。发现外周神经节与内脏器官之间存在精细的相互连接，形成了外周封闭的神经元回路。区分出三种类型的轴突作为主要成分。基于这种形态学基础，推测存在两种外周反射弧。
