像许多其他影响神经元放电的物质一样，腺苷必须首先与神经元膜上的特定受体结合。

Like many other agents that affect neuron firing, adenosine must first bind to specific receptors on neuronal membranes.

它由星形细胞瘤，少突胶质细胞瘤，室管膜瘤发展而来，它们是由神经外胚层细胞诱导的。

It developed from astrocytoma, oligodendroglioma, ependymoma, which were induced by neural ectoblast.

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

In some cells they're recycled, that is the cell is able to take up the neurotransmitter after it's released and restore it, but most often there are enzyme systems inside the pre-synaptic membrane where those neurotransmitters are synthesized.

在一些细胞中神经递质可以循环利用,这些细胞可以吸收,已经释放出的神经递质并重新储存起来,但更常见的是突触前膜中含有酶系统,在此合成神经递质
