During the headache phase, the trigeminal nerve plays a key role.

在头痛阶段，三叉经起到了关键作用。

The second T is for Trigeminal nerve.

第二个 T 代表三叉经。

Once activated, the trigeminal nerve transmits pain signals.

旦被激活，三叉经会传递痛觉信号。

Maybe the trigeminal nerve is less sensitive in certain demographics.

也许些人口中，他们的三叉经没有那么敏感。

Most commonly, the virus establishes a latent state within the trigeminal ganglia and the dorsal ganglia.

般情况下，病毒会在三叉经节和背经节维持潜伏状态。

This, in turn, helps cause brain arteries to dilate, which activates the trigeminal nerve, causing us pain.

这反来又会导致动脉扩张，从而激活三叉经，引起疼痛。

A specific cranial nerve, cranial nerve V, is the trigeminal nerve and it's responsible for the sensation in the face.

举例来说，第五经三叉经负责面部的感觉。

You can even use it for some pain conditions like trigeminal neuralgia.

你甚至可以将其用于些疼痛状况，比如三叉经痛。

It's been about 15 years I've been suffering with trigeminal neuralgia.

我患三叉经痛已有大约15年了。

Brain freeze happens when something cold hits the roof of your mouth where it triggers your trigeminal nerve.

冻发在冷的东西接触到口腔顶部时，那里会触发你的三叉经。

The sensory neurons of the face have their cell bodies in the trigeminal nuclei and those around the genitalia are located in the sacral nuclei.

面部感觉经元的胞体位于三叉经核内，殖器周围经元的胞体位于骶核内。

Its sensory neurons create a nerve cell cluster called trigeminal ganglion, located in the bones on the side of the face between the eyes and ears.

它的感觉经元组成了组经细胞簇，叫做三叉经节，位于两侧眼与耳中间的骨骼中。

These elements—cold weather, humidity, and a stimulated trigeminal nerve—combine to create something that isn't an odor, but a sensory experience you've come to associate with snow.

这些元素——寒冷的天气、湿度和被刺激的三叉经——共同创造了种不是气味的感官体验，但你已经将其与雪联系在起。

Now, the trigeminal nerve is a natural part of the body, so if it's the real cause of brain freeze then that means everyone should get it.

三叉经天就在我们的人体结构中，所以如果它真的是造成冰淇淋头痛的原因，那就意味着应该每个人都会有。

Since the trigeminal and sacral nuclei serve just one side of the face or body, herpes vesicles and ulcers develop on the ipsilateral or same side as the affected nuclei.

因为三叉经核和骶经核只支配脸部或身体的侧，所以，疱疹和溃疡也发在被感染的经核的同侧。

In one small study, 93% of migraine patients were also prone to brain freeze, which has led researchers to suspect that the trigeminal nerve also plays a key role in migraines.

在个小型研究中，93%的偏头痛患者也会发冰淇淋头痛。研究者猜测偏头痛是否与三叉经痛也有重要联系。

Just below that is the trigeminal nerve, the largest of the cranial nerves, which branches into three main strands — hence the 'tri' — and innervates the face and jaw muscles.

在三叉经下面是三叉经，最大的经，它分为三股——因此是“三”股——支配着面部和下巴肌肉。

The trigeminal nerve normally transmits touch, temperature, and other sensations from the skin to most of the face, part of the scalp, and some of the blood vessels and layers covering the cerebral cortex.

三叉经般会传递来自大部分脸部皮肤、部分头皮、以及覆盖大皮层的些血管和膜层的触觉、温度和其它感觉。
