The spinal cord is the bridge that connects the brain to peripheral nervous system.

脊髓是连接大脑和周围神经系统的桥梁。

The peripheral nervous system is basically anything that is outside of the skull or outside of the spinal column.

外周神经系统基本上是颅骨外或脊柱外的任何东西。

Your peripheral nervous system's mechano- and nociceptors provided that base sensation, or awareness that something had changed.

你的外周神经系统的机械感受器和伤害感受器提供了基本的感觉，或者说意识到某事发生了变化。

When nicotine binds to receptors in the peripheral nervous system, it increases blood pressure, heart rate, cardiac contractility, and gastrointestinal tract activity.

尼古丁在与周围神经系统的受体相结时，会引起血压升高，心率快，心肌收缩力强，胃肠道蠕动。

Which is why we designed the system to deliberately record from the peripheral nervous system.

这就是为什么我们将系统设计为故意从周围神经系统记录。

In the peripheral nervous system, they can cause peripheral neuropathy and paresthesia which is numbness and prickling sensations, particularly in the legs and feet.

在外周神经系统，它可以导致外周神经病变与感觉异常，比如麻木、刺痛的感觉，特别是在腿和脚部。

Now, so far, your body's response to the stimulus has been handled by the sensory, or afferent, division of your peripheral nervous system.

到目前为止，你身体对刺激的反应是由感觉或传入处理的，这属于你周围神经系统的分支部门。

It is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS).

它由中枢神经系统（CNS）和周围神经系统（PNS）这两个主要部分或两大分支组成。

Aminolevulinic acid, in particular, is the most likely culprit since it could cross the blood brain barrier and affect the central, autonomic, and peripheral nervous systems.

特别是氨基乙酰丙酸，是最可能的“嫌疑犯”，因为它可以跨越血脑屏障，影响中枢、自主和外周神经系统。

Today you got your first look at the peripheral nervous system, by learning how the afferent and efferent divisions provide information about, and responses to, pain.

今天你第一次看到了外周神经系统，通过学习传入和传出部门如何提供关于疼痛的信息和反应。

The peripheral nervous system's sensory nerve receptors spy on the world for the central nervous system, and each type responds to different kinds of stimuli.

周围神经系统的感觉神经受体为中枢神经系统窥探世界，每种类型对不同种类的刺激做出反应。

It's your peripheral nervous system that keeps things real, by putting your brain in touch with the physical environment around you, and allowing it to respond.

通过让你的大脑与你周围的物理环境接触，是你的外周神经系统让事情保持真实，并允许它做出反应。

So in this diagram, the peripheral nervous system starts basically where these branches come off the spinal cord, and you can see more peripheral nerves in the limbs here and here.

所以在这张图中，周围神经系统基本上从这些分支离开脊髓的地方开始，你可以在这里和这里看到更多的四肢周围神经。

In addition to working in sympathetic ganglia like this, it's also what the rest of your peripheral nervous system and lots of your central nervous system uses to communicate.

除了像这样在交感神经节工作之外，它也是你周围神经系统的其余部分和许多中枢神经系统用来交流的。

Your brain would be pretty useless if it weren't hooked up to the outside world. That's where the peripheral nervous system comes in, which we'll be spending the next few lessons exploring.

如果你的大脑不与外界相连，它将非常无用。这就是周围神经系统的来源，我们将在接下来的几节课中探索它们。

The Peripheral Nervous System. The peripheral nervous system includes 12 cranial nerves and 31 pairs of spinal nerves. It can be subdivided into the somatic and autonomic nervous systems.

3。周围神经系统;周围神经系统包括12条脑神经和31对脊神经。它可以细分为躯体神经系统和自主神经系统。

The central nervous system which includes the brain and the spinal cord, and the peripheral nervous system includes the nerves that fan out from the central nervous system to reach the skin, muscles, and organs.

中枢神级系统包括了脑和脊髓，周围神经系统包括了从中枢发出到达皮肤、肌肉和器官的神经。

Your autonomic system is the branch of your peripheral nervous system that regulates the functions of your internal organs, like your heart and stomach, and also controls your smooth and cardiac muscles, and your glands.

你的自主神经系统是你周围神经系统的分支，它调节你内部器官的功能，比如你的心脏和胃，也控制你的平滑肌和心肌，以及你的腺体。

Nerves in the peripheral nervous system can regenerate, and what happens is, let's say there's some injury to a nerve, the immune system is activated and it's kind of like New Year's Day in Times Square.

周围神经系统中的神经可以再生，然后就发生了这样的情况，比方说，某个神经受伤了，免疫系统被激活了，这就有点像在时代广场过新。
