In the presence of this ligand, this molecule, it's open, it allows transport of this ion, when the ligand is gone it doesn't.

配体存在的情况下通道才打开,允许这些离子穿过,配体离开后,这些离子就不能通过了

The one that's on the top here is called ligand-gated ion channel and an ion channel is a protein that sits in the surface of a cell.

最上面的这个叫作配体门控离子通道,离子通道是一类位于细胞表面的蛋白

In some cases it might be a ligand-gated ion channel.

有时受体可能是一个配体门控离子通道

The cells that take an electrical signal, which is coming down your nerve and convert it into a muscle contraction work this way, so 'neuro' nerve, muscle junctions act based on ligand-gated ion channels.

依靠相同的工作原理,细胞将来自于神经的,电信号传递到细胞收缩肌中,所以神经和肌肉关节运动,都基于配体门控离子通道
