Those receptors, some fraction of them,

这些受体其中一部分
are specific for the ligand that the pre-synaptic cell releases.

特异性地结合突触前细胞释放的配体
There's a lot of words here, long words,

我讲了一大堆生词长词
pre-synaptic, post-synpatic,

突触前突触后
but pre, post, you get the idea. Caitlin?

但是前和后的意思你们明白吧凯特琳
Just curious; before the ligand perimeter where are they stored?

只是好奇配体释放到周围前储存在哪
They're actually stored in these vesicles and

实际上它们就储存在小泡里
so--and they get into the vesicles in a variety of different ways.

它们通过不同方式进入小泡
In some cells they're recycled,

在一些细胞中神经递质可以循环利用
that is the cell is able to take up

这些细胞可以吸收
the neurotransmitter after it's released and restore it,

已经释放出的神经递质并重新储存起来
but most often there are enzyme systems inside the pre-synaptic membrane

但更常见的是突触前膜中含有酶系统
