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

多巴胺和乙酰碱。

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

这也是什么我们比较喜欢脑中释放乙酰碱时平稳和缓的感受。

Like all preganglionic fibers, these release acetylcholine, too.

像所有节前样，它们也释放乙酰碱。

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

乙酰碱与内皮细胞上的毒蕈碱受体结合，激活氧化氮合酶。

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碱，你会想记住这个名字的。

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

在这种情况下，副交感神经在海绵体间隙通过神经末梢释放乙酰碱。

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

在这个系统中，神经在节前突触中释放乙酰碱。

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碱能神经，因它们产生乙酰碱作神经递质。

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

饮食中碱的含量会影响大脑和中枢神经系统中乙酰碱的含量。

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。

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

受损的副交感神经不能释放乙酰碱，因此被激活的氧化氮合酶较少，产生的氧化氮也较少。

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

在间隙的侧，运动神经含有种称乙酰碱的神经递质。

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

该植物还含有破坏称乙酰碱的重要神经递质的化合物。

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

例如， 阻断神经递质乙酰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.

这些神经使用乙酰碱、多巴胺、5-羟色胺等神经递质。

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

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

Alright, so in this case, the patient's B cells inappropriately make antibodies that bind to nicotinic acetylcholine receptors on the muscle cells.

好了，在这种情况下，患者的B细胞产生了错误的抗体，该抗体和肌肉细胞中N碱受体相结合。

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，减少其表面的乙酰碱受体数量。

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

乙酰碱对这些神经的过度刺激会导致震颤和僵硬。

Even though this might be oversimplifying things a bit, the brain regions affected by HD have decreased GABA and acetylcholine, and increased dopamine levels.

尽管这可能有点过于简单化，但罹患HD患者的大脑内GABA和乙酰碱的水平减少，多巴胺水平增高。
