神经轴(neuraxis)(a-p轴)想象中的、从脑前端直贯脊椎的一条线。人们在描述神经系统中某一结构与另一结构之间的相互关系时,常常会使用“之前”或“之后”、“之上”或“之下”等术语。
...第45区)告诉我们,他们睡到了一起是一个错误,那么他们其实只给我们提供了非常有限的信息,或者说,那只是大脑的“神经轴”(neuraxis)当中的极小一部分关于这种行为的“评估结果””晴雯笑道:“我慌张的很,连扇子还跌折了,那里还配 打发吃 贾蓉忙送出来,又悄悄...

嗜银染色观察神经轴突再生。
Nerve axonal regeneration was observed by argentaffin staining.
观察了细小神经轴突膜电生理和物理特性参数。
Physiologic and physical parameters of small nerve fiber were measured.
每个神经细胞放出一条神经轴突,用来和目标细胞进行连接。
Each nerve cell sends out an axon, a long fiber, to make contact with a target cell and build connections.
Neurotransmitter release is stimulated by the electrical activity that reaches the end of the axon.
到达轴突末梢的电流变化,刺激了神经递质的释放
And then if you get a certain number, plus 60 or something, the neuron will fire and it fires along the axon, the thing to the right.
如果达到了一定的数量,比如超过60之类的,神经元便会产生神经冲动,神经冲动沿轴突传递,右边的是轴突
This process, which is shown schematically here, as a vesicle fusing with the cell membrane and then dropping its neurotransmitter only happens when an action potential reaches the end of the axon.
这一过程 扼要地展示在这里,小泡同细胞膜融合,释放其神经递质,这只发生在动作电位抵达轴突末梢时
