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感受。

In the central nervous system, nicotinic receptors are on pre-synaptic axon terminals of neurons, and when nicotine binds to them, it triggers the release of neurotransmitters like dopamine, acetylcholine, and glutamate, which is why it's considered an acetylcholine agonist.

在中枢系统中，烟碱受体分布于突触前元轴突末端，当尼古丁与受体结合后，会触发多巴胺、乙酰胆碱、谷氨酸盐等递质释放，因此尼古丁被认为是一种乙酰胆碱受体兴奋剂。

For now you learned that your sympathetic nervous system controls your body's stress response and how the signals in your sympathetic nervous system travel to an effector, using the neurotransmitters acetylcholine in the ganglion and norepinephrine at the effector.

现在你知道了你交感系统控制你身体压力反，以及交感系统中信号如何传递到效物，使用节中递质乙酰胆碱和效物处去甲肾上腺素。

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患者大脑内GABA和乙酰胆碱水平减少，多巴胺水平增高。

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

多巴胺和乙酰胆碱。

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。

Once nicotine is absorbed into the bloodstream, it binds to a type of acetylcholine receptor, called a nicotinic acetylcholine receptor - also called a nicotinic receptor - which is found throughout the body and brain.

一旦尼古丁进入血液循环，它就会和一种乙酰胆碱受体结合，也称烟碱型乙酰胆碱受体或烟碱受体；这类受体广泛分布于身体和大脑中。

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连锁反，最终导致肌肉收缩。

So, that acetylcholine crosses the synapse and, if there's enough of it, it can stimulate action potentials in several neurons on the other end — in the postganglionic fibers.

乙酰胆碱穿过突触，如果有足够乙酰胆碱，它可以刺激另一端几个元动作电位——在节后纤维中。

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

你身体使用胆碱产一种叫做乙酰胆碱递质，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B细胞产了错误抗体，该抗体和肌肉细胞中N胆碱受体相结合。

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

在这两个系统中，元在节前突触中释放乙酰胆碱。

Since usually there's this balance of signaling between dopamine and acetylcholine, a loss of dopamine reaching the striatum increases the relative amount of acetylcholine signalling there.

由于多巴胺和乙酰胆碱之间有一种平衡，多巴胺减少信号传到纹状体，导致乙酰胆碱信号发出相增加。

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

饮食中胆碱含量会影响大脑和中枢系统中乙酰胆碱含量。

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。

Motor symptoms respond to drugs used to treat Parkinson's disease, like levodopa, a dopamine analogue, while cognitive symptoms may improve with drugs for Alzheimer's disease, like donepezil, which increases acetylcholine availability.

针对运动障碍，可使用与帕金森病类似药物，比如多巴胺类似物左旋多巴，而使用类似阿尔茨海默病药物，可以改善认知症状，比如多奈哌齐，它能增加乙酰胆碱供给。

Once acetylcholine receptors are bound by the antibody, they are unable to bind to acetylcholine, and therefore don't respond to the " contract" signal from the central nervous system.

一旦Ach受体与抗体结合，就无法与ACh结合，因此对中枢系统“收缩”信号没有反。

When the signals reach the synapses inside the ganglia, the nerve fibers then release a neurotransmitter — called acetylcholine, known to its friends as ACh.

当信号到达节内突触时，纤维会释放一种递质——乙酰胆碱，朋友们称之为 ACh。

It's possible that this is because helper T cells, which originate in the thymus, help B cells make antibodies to the acetylcholine receptor.

这可能是因为起源于胸腺T细胞，帮助B细胞产ACh受体抗体。

One example is anticholinergics, which suppress the activity of acetylcholine, a neurotransmitter.

一个例子是抗胆碱能药物，它们抑制乙酰胆碱这种递质活性。
