The facial nerve exits the skull through a tiny hole called the stylomastoid foramen.

面由一个叫做茎乳孔小洞出颅。

Firstly, the two roots fuse to form the facial nerve.

首先，面分。

The facial nerve then exits the facial canal and the cranium via the stylomastoid foramen.

然后面通过茎乳孔离开面管和颅骨。

Certain conditions, such as Bell's palsy and certain types of tumors can paralyze facial nerves and muscles.

某些情况，如贝尔氏麻痹和某些类型肿瘤，会使面部和肌肉瘫痪。

Bioprinted bladders have also been successfully implanted, and printed tissue has promoted facial nerve regeneration in rats.

也已成功植入过生物打印膀胱，打印出来组织还成功促进了鼠脸部再造。

The part of the facial nerve that arises from the sensory root is sometimes known as the intermediate nerve.

面起源于感觉部分有时被称中间。

So if you lick an ice cream cone - that's the facial nerve registering the flavor!

所以当你舔冰激凌球时，是面在传递它味道。

Bell's palsy occurs when there's a disruption of the facial nerve from an unknown cause.

贝尔麻痹发生于面受损，且原因不明。

The main trunk of the nerve, now termed the motor root of the facial nerve, continues anteriorly and inferiorly into the parotid gland.

主干，现在被称面运动根，向前和向下延伸到腮腺。

In some people, there's also dryness of the affected eye or mouth because the facial nerve innervates the lacrimal, submandibular, and sublingual glands.

某些病例也会有受累侧眼干、口干，由于面配泪腺、颌下腺和舌下腺。

This can end up causing Chvostek's sign, which is when facial muscles twitch after the facial nerve is lightly finger tapped 1 cm below the zygomatic process.

这最终会导致Chvostek征，即在颧骨下方1cm处轻轻按压面，面部肌肉会发生抽搐。

From there, the facial nerve branches off to different facial muscles that help with facial expression, like the ones you use while whistling to your favorite song.

在此处，面分到不同面部肌肉来控制面部表情，包括那些你吹小曲儿时用到面部肌肉等。

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，即面，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，叫做面管。

The spontaneous firing of neurons also leads Chvostek's sign, which is when facial muscles twitch after the facial nerve is lightly finger tapped 1 cm below the zygomatic process.

元自发放电也会产生Chvostek征，就是在颧骨突起处下方1厘米处用手指轻轻敲打面后，产生面部肌肉抽搐现象。

Regardless of the cause, when the facial nerve isn't able to conduct the brain's signals, the result is that there's weakness or paralysis of the facial muscles.

不论病因如何，当面不能传递来自大脑信号，就会导致面部肌肉无力或瘫痪。

The facial nerve also innervates the sublingual and submandibular glands, which secrete saliva, as well as the lacrimal gland which produces tears, and mucous membranes of the nose, mouth, and nasopharynx.

面同时也配着舌下腺和下颌下腺，它们可以分泌唾液；以及产生眼泪泪腺，还有口、鼻、鼻咽粘膜。

So that means that each facial nerve contains motor information for the lower face coming from the contralateral motor cortex, and motor information for the upper face coming from both motor cortices.

也就是说，每条面包含种运动信号：1.控制下半脸运动信号，来自对侧运动皮质；2.控制上半脸运动信号，来自双侧运动皮质。

The diagnosis of a Bell's palsy is based on identifying that the problem is with the facial nerve and not finding an alternative explanation like a stroke or brain tumor.

贝尔麻痹诊断依靠识别面受损，且无中风或脑部肿瘤等病因。

After that there's the abducens, which stimulates the muscles that let your eyes do this -- from side to side, followed by the facial nerve, which operates the muscles that make most facial expressions possible.

然后是外展肌，它刺激肌肉让你眼睛这样做——从一边到另一边，然后是面，它操纵肌肉，使大多数面部表情成可能。

The underlying cause of cranial nerve damage is idiopathic which means it's unknown, so when there's facial nerve a paralysis from a known cause like a stroke, a tumor, or trauma, it's not considered a Bell's palsy.

该颅受损是特发性，即原因不明，所以有明确病因（如中风、肿瘤、外伤）面麻痹不属于贝尔麻痹。
