The synapse is just this anatomical region of contact between two adjacent cells in the nervous system.

突触是解剖学上,神经系统相邻两细胞的连接区域

Another characteristic of the synapse is that the post-synaptic membrane, the membrane of the cell which is going to receive the signal has receptors on it.

突触的另一个特征是,它们都有一个突触后膜,这个膜上含有受体,可以接受信号

This infinitesimal gap-- and this gap is known as a synapse-- and what happens is when a neuron fires, an axon sends chemicals shooting through the gap.

这个极小的缝隙,这个缝隙就叫做突触,当神经元产生神经冲动后,轴突会释放出能够穿透缝隙的化学物质

Well, that specialized region - now in this diagram here, this is the axon of one cell, the first cell in a sequence and that axon meets the dendrite of another cell at a special region called a synapse.

图中这里的这一特定区域,是一个细胞的轴突,是这一列中的第一个细胞,而轴突,和另一个细胞的树突,在一个叫做突触的地方相遇

One is that there's a physical space in between the two cells, so the axon of what's called the pre-synaptic neuron, or the neuron that's bringing a signal into the synapse, the axon terminal is physically separated from the dendrite of the next cell.

一是两个细胞间有一定的物理空间,所谓的突触前神经元,也就是将信号传递到突触的神经元的,轴突的末梢,同下一个细胞的树突间被物理性分离开
