There are two important chemicals found in all our brains - dopamine and acetylcholine.

多巴胺和乙酰胆碱。

In both systems, neurons release acetylcholine, or ACh, in their preganglionic synapses.

在这两个系统中，神经元在节前突触中释放乙酰胆碱。

That's why we prefer the more slow-burn feeling we get when our brains release acetylcholine.

这也是为什么我们比较喜欢脑中释放乙酰胆碱时平稳和缓的感受。

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。

Like all preganglionic fibers, these release acetylcholine, too.

像所有节前纤维一样，它们也释放乙酰胆碱。

In both cases, the parasympathetic nerve fibers in the cavernosal spaces release acetylcholine from their nerve endings.

在这两种情况下，副交感神经纤维在海绵体间隙通过神经末梢释放乙酰胆碱。

If you haven't heard of acetylcholine yet, you're gonna wanna remember that name.

如果你还没听说过乙酰胆碱，你会想记住这个名字的。

The amount of choline in the diet influences how much acetylcholine is available in the brain and central nervous system.

饮食中胆碱的含量会影响大脑和中枢神经系统中乙酰胆碱的含量。

Binding of acetylcholine to its receptor activates a chain reaction in the muscle cell that ultimately results in muscle contraction.

ACh与其受体结合激活了肌肉细胞的连锁反应，最终导致肌肉收缩。

On one side of the gap, the motor neuron contains a neurotransmitter called acetylcholine.

在间隙的一侧，运动神经元含有一种称为乙酰胆碱的神经递质。

For example, drugs that block receptors for the neurotransmitter acetylcholine can cause impressive dilation.

例如， 阻断神经递质乙酰胆碱受体的药物可以引起令人印象深刻的扩张。

These neurons use such neurotransmitters as acetylcholine, dopamine, serotonin and others.

这些神经元使用乙酰胆碱、多巴胺、5-羟色胺等神经递质。

Damaged parasympathetic nerve fibers can't release acetylcholine, so there's less nitric oxide synthase activation, and less nitric oxide is produced.

受损的副交感神经纤维不能释放乙酰胆碱，因此被激活的一氧化氮合酶较少，产生的一氧化氮也较少。

Most neurons in the cerebral cortex are called cholinergic neurons, because they produce acetylcholine.

大脑皮层中的大多数神经元为胆碱能神经元，因为它们产生乙酰胆碱作为神经递质。

The plant is also loaded with compounds that disrupt the vital neurotransmitter called acetylcholine.

该植物还含有破坏称为乙酰胆碱的重要神经递质的化合物。

The overstimulation of these neurons by acetylcholine then causes tremors and rigidity.

乙酰胆碱对这些神经元的过度刺激会导致震颤和僵硬。

Your body uses choline to produce a neurotransmitter called acetylcholine, which plays key roles in learning, memory, attention, motivation, and healthy sleep.

你的身体使用胆碱产生一种叫做乙酰胆碱的神经递质，它在学习、记忆、注意力、动力和健康睡眠中起着关键作用。

The activation of complement causes inflammation and destruction of the muscle cells and reduces the amount of acetylcholine receptors on the surface.

补体激活引起炎症反应，破坏肌肉细胞，减少其表面的乙酰胆碱受体数量。

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。

This triggers the release of a hormone called acetylcholine that decreases the heart rate and gradually winds down the panic attack.

这会触发一种叫做乙酰胆碱的激素的释放，这种激素会降低心率并逐渐平息惊恐发作。
