The lingual nerve (LN) is a branch of the mandibular division of the fifth cranial nerve, the trigeminal. It primarily carries sensory fibers from the lingual gingiva, mucous membranes of the floor of the mouth, sublingual gland, and the anterior two-thirds of the tongue. Recent studies have explored and reclassified the five branches of the LN as branches to the isthmus of the fauces, lingual branches, sublingual nerves, posterior branch to the submandibular ganglion, and branches to the sublingual ganglion. The knowledge of the LN anatomy and its variants is clinically relevant to avoid its injury during oral procedures. The objective of this paper is to review the literature on the LN and to describe the anatomy, its course, and its functions.
舌神经（LN）是第五对脑神经（三叉神经）下颌支的一个分支。它主要携带来自舌侧牙龈、口腔底部黏膜、舌下腺以及舌前三分之二的感觉纤维。最近的研究对舌神经的五个分支进行了探索和重新分类，分别为通向咽峡的分支、舌支、舌下神经、至下颌下神经节的后支以及至舌下神经节的分支。了解舌神经的解剖结构及其变异在临床上对于避免口腔手术中损伤该神经具有重要意义。本文的目的是回顾关于舌神经的文献，并描述其解剖结构、走行及其功能。
