In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.

三叉神經 （trigeminal nerve）即第五對 腦神經，是面部最粗大的神經，屬 混合神經 （含 運動神經 且含 感覺神經），大部分為感覺纖維，小部分為運動纖維，因有三大支而得名。 三叉神經的感覺部分收集來自 面部 和 頭部 的資訊，運動部分則控制 咀嚼肌。 三叉神經的運動部分從腦橋與腦橋臂交界處出腦，再併入 下頜神經，一同經 卵圓孔 穿出 顱部。 而它的感覺部分的胞體組成位於 顳骨 岩部尖端的 三叉神經節，三叉神經節又分出三條分支，第一分支為 眼神經 （ophthalmic …

2023年7月25日 · Learn the anatomy of ophthalmic nerve with our videos, quizzes, articles, and labeled diagrams: Like the ophthalmic branch, the maxillary division of the trigeminal nerve (CN V2) is a purely sensory entity that carries impulses from the midface. It has a middle meningeal branch that detects stimuli from the dura of the middle cranial fossa.

2025年2月12日 · The trigeminal nerve (CN V) is the fifth paired cranial nerve. It is also the largest cranial nerve. In this article, we shall look at the anatomy of the trigeminal nerve – its course, functions and clinical correlations. Explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way.

Proprioception for the temporomandibular joint is absent when there is a lesion of the mandibular division. The motor division of the nerve supplies the muscles of mastication: masseter, temporal, pterygoid, mylohyoid, and digastric. These muscles produce elevation, depression, protrusion, retraction, and the side-to-side movements of the mandible.

2025年1月24日 · The trigeminal nerve is the fifth (CN V) cranial nerve and its primary role is relaying sensory information from the face and head, although it does provide motor control to the muscles of mastication via the mandibular division (TA: nervus trigeminus or nervus cranialis V).

運動覺(Kinesthesis senses，可由意識察覺) 屬於感覺神經，負責偵測舌頭感覺。 但會借道給CN 7顏面神經的分枝去支配唾腺的下頷下腺和舌下腺. 以電子郵件傳送這篇文章BlogThis！ 分享 …

2024年4月20日 · CN V provides most of the face's sensory innervation and the mastication muscles' motor stimulation. The nerve's 3 main branches are the ophthalmic (V1), maxillary (V2), and mandibular (V3) nerves. These branches join at the trigeminal ganglia within the Meckel cave in the middle cranial fossa.

2021年5月19日 · Cranial nerve 5 (CN5) , is the trigeminal nerve. The function of the trigeminal nerve includes; sensation of different parts of the face, and some movements of the head, jaw and nasal cavity. Cranial nerve 7, the facial nerve is responsible for the …
