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，由于面神经支配泪腺、颌下腺和舌下腺。

Causes It is caused by dental infection or tooth abscess, involving molars and premolars, as well as submandibular sialadenitis, injuries to oral mucosa, and mandibular fracture.

病因原因是牙齿感染或牙齿脓肿，累及磨牙和前磨牙，同时伴有下颌下涎腺炎、口腔黏膜损伤和下颌骨折。

Its location is the infection of submandibular space, which is divided into two compartments by mylohyoid muscle, sublingual compartment (above muscle) , submaxillary and submental compartment (below muscle) .

其位置为颌下腔感染，颌下腔被下颌舌骨肌、舌下腔室（肌上）、上颌下腔室和颏下腔室（肌下）分为两个腔室。

These exocrine glands produce a fluid called saliva, which is released, from the parotid gland, submandibular gland and sublingual gland on each side of the mouth.

这些外分泌腺产生一种称为唾液的液体，唾液从嘴两侧的腮腺，下颌下腺和舌下腺中释放出来。

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.

面神经同时也支配着舌下腺和下颌下腺，它们可以分泌唾液；以及产生眼泪的泪腺，还有口、鼻、鼻咽的粘膜。

At the same time, the three sets of salivary glands - the sublingual, below the tongue, the submandibular, below the mandible, and the parotid gland, which is near the ear, all secrete saliva to lubricate the food.

与此同时，三组唾液腺：舌下腺（位于舌下）、下颌下腺（位于下颌下）、腮腺（位于耳部附近）等同时分泌唾液润滑食物。
