We'll start that next week, with a white-knuckle ride through your sympathetic nervous system.

下周我们将开始先体验一下你交感神经系统的紧张刺激。

The HPA Axis is essentially the endocrine system's companion to the sympathetic nervous system.

HPA 轴本质上是内分泌系统与交感神经系统的伴侣。

Adderall also causes the release of norepinephrine, which activates the sympathetic nervous system, initiating your fight-or-flight response.

Adderall 还会导致去甲肾上腺素的释放，从而激活交感神经系统，引发你的“战或逃”反应。

The sympathetic nervous system is made up of a collection of nerves that extend through the body, including the skin.

交感神经系统由遍布身体的神经组成，包括皮肤。

One of them is dedicated to amping you up and preparing you for activity — that's your sympathetic nervous system.

其中一个专门为你兴奋，让你为活动做好准备——那是你的交感神经系统。

Stress activates your sympathetic nervous system, which increases your heart rate and moderates your blood pressure using a hormone called cortisol.

压力会激活交感神经系统，利用一种叫皮质醇的激素增加心率及缓和血压。

Well, the first half of your breath, the inhale, influences your sympathetic nervous system, which controls your fight or flight response.

呼吸的前半部分，吸气，会影响你的交感神经系统，该系统控制战斗或逃跑反应。

This one's called norepinephrine. And it is always norepinephrine that's released from postganglionic fibers in the sympathetic nervous system.

这个叫做去甲肾上腺素。交感神经系统节后纤维释放的永远是去甲肾上腺素。

Neurotransmitters then alert the sympathetic nervous system of the perceived threat.

然后神经递质提醒交感神经系统感知到的威胁。

We have parasympathetic nervous system and our sympathetic nervous system.

我们有副交感神经系统和交感神经系统。
