Once activated, the trigeminal nerve transmits pain signals.

一旦被激，三叉会传递痛觉信号。

Maybe the trigeminal nerve is less sensitive in certain demographics.

也许一些人口中，他们三叉没有那么敏感。

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

在头痛阶段，三叉起到了关键作用。

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

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，第五对脑三叉负责面部感觉。

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

当寒冷东西击中您上颚并触发您三叉时，就会发生大脑冻结。

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.

面部感觉胞体位于三叉核内，生殖器周围胞体位于骶核内。

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.

它感觉组成了一组细胞簇，叫做三叉节，位于两侧眼与耳中间骨骼中。

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.

三叉天生就在我们人体结构中，所以如果它真是造成冰淇淋头痛原因，那就意味着应该每个人都会有。

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.

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

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.

因为三叉核和骶核只支配脸部或身体一侧，所以，疱疹和溃疡也发生在被感染核同侧。

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.

在一个小型研究中，93%偏头痛患者也会发生冰淇淋头痛。研究者猜测偏头痛是否与三叉痛也有重要联系。

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.

三叉一般会传递来自大部分脸部皮肤、部分头皮、以及覆盖大脑皮层一些血管和膜层触觉、温度和其它感觉。
