Your adrenal gland releases the stress hormones cortisol, epinephrine, also known as adrenaline, and norepinephrine.

你的肾上腺会释放压力荷尔蒙皮质醇，肾上腺素，以及去甲肾上腺素。

And releases epinephrine and norepinephrine into the blood making your heart pump faster.

并会向血液中释放肾上腺素和降肾上腺素使你的跳加速。

" Get me epinephrine! " the doctor said.

“给我肾上腺素！ ”医生说道。

Peripheral dopa decarboxylase also exists, which can metabolize levodopa into dopamine before it gets through the blood brain barrier, and—via additional enzymes— metabolize it into other catecholamines like epinephrine, which can cause unwanted side effects like arrhythmias.

体内还有外周多巴脱羧酶，可以多巴穿过血脑屏障前将其转换为多巴胺；然后，通过其他酶将其转换为其他儿茶酚胺，如肾上腺素，可以导致不良的副作用，如律失常。

On the smooth muscle cells controlling some blood vessels, there are receptors called alpha receptors — when norepinephrine, or epinephrine, bind to those receptors, they make those smooth muscle cells contract, thereby restricting blood flow.

控制一些血管的平滑肌细胞上，有一种叫做α受体的受体——当去甲肾上腺素或肾上腺素与这些受体结合，使这些平滑肌细胞收缩，从而限制血液流动。

Diagnosis of neuroblastoma usually starts with testing for HMA and VMA in the blood or urine, since high levels those metabolites may indicate tumors that secrete epinephrine and norepinephrine.

对于神经母细胞瘤的诊断，通常先检测血或尿中的HMA和VMA，这是因为代谢产物含量高可提示肿瘤释放肾上腺素和去甲肾上腺素。

Stress may also be a contributing factor, since it ramps up production of epinephrine, a molecule connected with the fight-or-flight response that can cause muscle contractions or spasms.

压力也可能是一个促成因素，因为会增加肾上腺素的产生，这是一种与“战斗或逃跑反应”相关的分子，可能导致肌肉收缩或痉挛。

Doctors advise people with the allergy to stop eating meat and other foods that cause the reaction and to have epinephrine available to them at all times.

医生建议过敏患者停止食用肉类和其他引起过敏反应的食物，并随准备注射肾上腺素。

With such a long fast, hormones such as glucagon and epinephrine are released to increase blood glucose levels and more importantly, break down more fat.

如此长间的禁食，血液中诸如胰高血糖素和肾上腺素等激素水平会升高，以增长血糖值，更重要的是可以分解更多脂肪。

Three were treated with the medicine epinephrine to calm the reaction, and one dropped out of the study as a result.

其中三人接受了肾上腺素药物治疗以平息反应，一人因此退出了研究。

This is because the nicotine in cigarettes released epinephrine and norepinephrine, which increase your heart rate and narrowed blood vessels.

这是因为烟草中的尼古丁会释放肾上腺素和去甲肾上腺素。

In severe cases, a peanut reaction can kill, unless the child is given an injection of epinephrine.

严重的情况下，花生的反应会致命，除非给孩子注射肾上腺素。

Even the epinephrine hadn't been able to restart Fury's heart.

即便是肾上腺素也没能让弗瑞的脏重新跳动。

And you learned that other signals can go right to the adrenal glands, where norepinephrine and epinephrine are secreted as hormones.

你了解到其他信号可以直接到达肾上腺，去甲肾上腺素和肾上腺素那里以荷尔蒙的形式分泌。

In states of stress, like an infection, the body releases epinephrine, which in turn stimulates the release of glucagon.

压力状态下，比如发生感染，身体会产生肾上腺素，从而刺激胰高血糖素的释放。

But on smooth muscle cells that control other blood vessels, there are lots of beta receptors for epinephrine and norepinephrine, and when they are activated, they make the muscles relax, letting more blood flow through.

但是控制其他血管的平滑肌细胞上，有许多肾上腺素和去甲肾上腺素的β受体，当被激活，使肌肉放松，让更多的血液流过。

The sympathetic neurons releases norepinephrine, also called noradrenaline, and the cells of the adrenal medulla release norepinephrine and epinephrine, also called adrenaline.

交感神经元释放去甲肾上腺素，而肾上腺髓质细胞释放去甲肾上腺素与肾上腺素。

Cortisol also helps to maintain the blood pressure by increasing the sensitivity of peripheral blood vessels to catecholamines- like epinephrine and norepinephrine, and this narrows the blood vessel lumen.

皮质醇也帮助维持血压，增加周围血管对如肾上腺素和去甲肾上腺素等儿茶酚胺的敏感性，这会缩小血管腔。

After the game is over, and the hormones are no longer needed, epinephrine and norepinephrine break down into metabolites like homovanillic acid or HMA, and vanillylmandelic acid, or VMA.

比赛结束而不再需要这些激素，肾上腺素和去甲肾上腺素分解成代谢产物，例如高香草酸（HMA）和香草扁桃酸（VMA）。

And a molecule of epinephrine ... it has no memory of its origin.

还有一个肾上腺素分子… … 没有关于起源的记忆。
