突触间隙 synaptic cleft 在化学传递性突触中,在突触前神经末梢和突触下膜之间,有与通常的细胞间隙同样的间隙存在,称此为突触间隙。
突触间隙(synaptic cleft) 位于突触前膜与突触后膜之间的间隙。 5 当突触前神经元发出的神经冲动沿轴膜传导至轴突终末时,引发突触前膜发生一系列变 化,突触...

一般来说,动作电位到达突触节会导致神经递质释放到突触间隙。
In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the synaptic cleft.
同时突触超微结构也出现一定的改变,如:突触小泡减少和突触间隙变窄。
The ultrastructural alterations could also be found in synapse, for example, decreased synaptic vesicle, narrow synaptic cleft.
目的:探讨面神经麻痹面肌运动点的兴奋性与运动终板次级突触间隙的关系。
Objective: Our purpose was to study the relationship between the excitability of facial muscular motor point and the secondary synaptic space of motor terminal plate in facial paralysis.
When these vesicles dump their contents into the synaptic cleft, the concentration of these ligands rise.
当这些小泡将其内含物释放入突触间隙,这些配体的浓度即增加
It's called the synaptic cleft and it's filled with extracellular fluid.
这一空间叫做突触间隙,中间充满了细胞外液
When an action potential comes down this pre-synaptic axon, when it reaches this point here, it sets off the process of these vesicles dumping their content into the synaptic cleft.
当动作电位到达轴突的突触前膜时,当到达这一点时 小泡就将其内含物,排放到突触间隙中去
