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，第五对脑神经三叉神经负责面部感觉。

Even rarer is the cephalic tetanus, which is limited to the muscles applied by the 12 cranial nerves only.

更罕见是头部型破伤风，即痉挛仅局限于12对颅神经肌肉。

There are 12 of these cranial nerves, and they vary in terms of what kinds of neurons they contain.

一共有 12 条颅神经，它们所含神经元各不相同。

Some of your cranial nerves also carry motor fibers that control voluntary functions, like moving your eyeballs around.

你一些脑神经还携带运动纤维，控制自发功能，比如移动眼球。

Peripheral nerves that emerge from the brain and brainstem are called cranial nerves, and there are a total of 12 pairs of cranial nerves.

其中，由脑和脑干发出周围神经叫做颅神经，一共有12对。

The cranial nerves can also be involved, and that can cause symptoms like double vision and difficulty speaking.

脑神经受损时，会导致复视和说话困难等症状。

And, you know, just to keep things interesting, some of your cranial nerves carry both motor and sensory neurons.

为了让实验更有趣一些，脑神经同时携带运动神经元和感觉神经元。

What is the shortest cranial nerve in the human body?

人体脑神经是什么？

The olfactory nerve, which aids with smell, is the shortest cranial nerve.

嗅觉神经有助于嗅觉，是脑神经。

Peripheral nerves that originate from the brain are called cranial nerves, and they're in charge of motor and sensory innervation of the head and neck.

从脑发出周围神经叫做脑神经，着头颈运动和感觉。

The PNS is a vast network of spinal and cranial nerves that are linked to the brain and the spinal cord.

PNS是由连接到脑和脊髓脊神经和脑神经构成巨大网络。

PNS consists of total 43 pairs of nerve, among which 12 originate in brain, named as cranial nerves and 31 originate from spinal cord, hence called as spinal nerves.

周围神经系统由 43 对神经组成，其中 12 对起源于脑，称为脑神经，31 对起源于脊髓，故称为脊神经。

The seventh cranial nerve, the facial nerve, emerges from the brainstem, and then enters the temporal bone where it travels through a narrow, Z-shaped canal, called the facial canal.

第七对颅神经，即面神经，由脑干发出，然后进入颞骨，在这里它穿过了一个狭窄Z字形管道，叫做面神经管。

You might notice that, up until the auditory nerve, the cranial nerves mostly control organs in the front of the cranium — mainly the eyes and facial muscles.

你可能会注意到，直到听觉神经为止，脑神经主要控制头盖骨前部器官——主要是眼睛和面部肌肉。

Taste begins with taste receptor epithelial cells, rather than nervous cells, where tastants bind to receptors that trigger action potentials to four different cranial nerves that tell you: PIZZA.

味觉始于味觉受体上皮细胞，而不是神经细胞，在神经细胞中，味觉受体与触发动作电位受体结合，这四种不同脑神经告诉你：这是 PIZZA。

When we get dunked, a branch of one of our cranial nerves senses the temperature and pressure change and alerts our brain to begin rationing oxygen.

当我们被扣篮时，我们脑神经一个分会感知温度和压力变化，并提醒我们大脑开始给氧气。

For peripheral nerves, the cell body can either be located in the spinal cord where it's called a spinal nerve or the brain where it's called a cranial nerve.

周围神经神经元胞体，若位于脊髓中，就称为脊神经；若位于脑中，则称为脑神经。

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.

在三叉神经下面是三叉神经，大脑神经，它分为三股——因此是“三”股——着面部和下巴肌肉。

Starting at the top, the first cranial nerve you encounter is the olfactory nerve, which takes scent information gathered by the nose and sends it to the brain.

从顶部开始，你遇到第一个脑神经是嗅觉神经，它接收鼻子收集气味信息并将其发送到大脑。

The 10 out of the 12 cranial nerves originate from the brainstem, and mainly control the functions of the anatomic structures of the head with some exceptions.

12条颅神经中有10条起源于脑干，除个别外，主要控制头部解剖结构功能。
