免疫电镜还显示有TH阳性神经元胞体和轴突末梢，后者可作为突触前成分与TH阴性结构形成突触。

Especially, there were TH-like positive cell bodies and axonal endings which formed synapses as presynaptic elements with th negative postsynaptic structures.

此外，SP阳性轴突末梢还可与NT阳性神经元的树突棘形成对称性轴-棘突触及与NT阳性轴突形成对称性轴-轴突触。

In addition, SP-positive axonal terminals established symmetric axospinous synapses with NT-positive dendritic spines, and axo-axonic synapses with NT-positive axons.

神经垂体类似神经组织，有神经胶质细胞、神经纤维、神经末梢及轴突内的神经内分泌颗粒。

The neurohypophysis shown here resembles neural tissue, with glial cells, nerve fibers, nerve endings, and intra-axonal neurosecretory granules.

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

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

another thing that you'd find if you looked inside the axon terminals of any of these pre-synaptic membranes, you'd find lots of vesicles or some membrane bound compartments that contain special chemicals called neurotransmitters.

如果你仔细观察,突触前膜的轴突末梢内部,你会发现很多小泡,即膜包被的结构,包含有称为神经递质的特殊化合物
