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。

We also touched on hormone cascades, and how the HPA axis effects your stress response.

我们还谈到了荷尔蒙级联，以及 HPA 轴如何影响你的压力反应。

And that's great! Your HPA axis is super-useful when you're under stress and need to take action.

这太棒了！当你有压力并需要采取行动时，你的 HPA 轴非常有用。

The hippocampus also inhibits the activity of the HPA axis, so when it weakens, so does your ability to control your stress.

海马体也抑制了下丘脑肾上腺轴的活动，所以当它变弱，你控制压力的能力也随之变弱了。

When your brain detects a stressful situation, your HPA axis is instantly activated and releases a hormone called cortisol, which primes your body for instant action.

当你的大脑检测到压力情况，你的下丘脑垂体肾上腺轴立刻会被激活，并释放一种叫做皮质醇的激素， 提醒你的身体做好立即行动的准备。

When this alarm sounds, the hypothalamic, pituitary, and adrenal systems, known as the HPA axis, work together to send signals to the parasympathetic nervous system.

当此警报响起时，称为 HPA 轴的下丘脑、垂体和肾上腺系统会协同工作，向副交感神经系统发送信号。
