软体动物的内脏神经中枢,有1对,位于头神经节、侧神经节、足神经节的后方。在有肺类中与足神经节合并,在斧足类的原始类型中明显地分为左右两个,在高等类型左右直接相连。伴随头神经节的退化,内脏神经节发达,在蓑贝、海菊类可见两者融合,头足类则位于腹侧,与足神经节、侧神经节合一,界限不清。
结果提示,躯体与内脏输入可通过分叉初级传入,在同一个A型脊神经节神经元上会聚。
These results indicate that somatic and visceral input may converge on single type a spinal ganglion neurons via dichotomizing primary afferents.
研究表明,来自体表和内脏的信息可在脊神经节及从脊髓到大脑皮层的各级中枢发生汇聚。
Some researches indicate that the information coming from the body surface and viscera can be assembled at all levels of centers from spinal ganglion to cerebral cortex.
目的探讨支配腹部内脏器官的交感节后神经元在腹腔-肠系膜上神经节内的代表区。
