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。

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。

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合时，会引起血压升高，心率加快，心肌收缩力增强，胃肠道蠕动增加等。

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。

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。

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。

The central nervous system's main game is integrating the sensory information that the peripheral system collects from all over the body, and responding to it by coordinating both conscious and unconscious activity.

中枢神经系统的主要工作是整合外围系统从全身收集的感觉信息，并通过协调有意识和无意识的活动来回应它。

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。

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 vagus nerves work as a two-way street, ferrying incoming sensory information from the peripheral system to the brain, and transmitting outgoing motor instructions from the brain to the rest of the body.

迷走神经是双向的，将传入的感觉信息从周围系统传送到大脑，并将传出的运动指令从大脑传送到身体的其他部位。

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。

By breaking it down you can get things into the brain, but also by breaking it down, now things can go from your brain out into your circulation, to your peripheral system, which includes your immune system.

通过破坏它，你就能将药物送入大脑，但同样的一些东西也会借大脑进入身体循环，并到达包括免疫系统在内的其他外部系统。
