The acetylcholine bind to muscarinic receptors on endothelial cells, which activates the enzyme nitric oxide synthase.

乙酰胆碱与内皮细胞上的毒蕈碱受体结合，激活一氧化氮合酶。

This is where Antimuscarinic agents come into play by blocking the muscarinic acetylcholine receptors and cholinergic nerve activity.

这就是抗真菌剂通过阻断毒蕈碱乙酰胆碱发挥作用的地方受体和胆碱能神经活动。

But - those same airways also have muscarinic receptors which can get stimulated by parasympathetic nerves, causing a decrease in the diameter of airways.

但是这些气道也有M胆碱受体，副交感神经也可以激动它们，使气道收缩。

Now, as I mentioned at the beginning of this lecture, in Parkinson's disease, dopamine depletion leads to increased acetylcholine release, which then activates muscarinic receptors located on the neurons responsible for smooth motor control.

现在，正如我在这堂课开始时提到的，在帕金森氏症中，多巴胺耗尽导致乙酰胆碱释放增加，然后激活毒蕈碱受体位于负责平稳运动控制的神经元上。
