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.

2023年7月25日 · 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.

2024年4月20日 · The trigeminal nerve is the 5th cranial nerve (CN V) and the largest of the cranial nerves (see Image. Cranial Nerves in the Orbit). 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.

2024年7月22日 · Your trigeminal nerve, also known as cranial nerve 5 or CN V, is a large, three-part nerve in your head that sends signals from your brain to parts of your face, and vice versa. You have two trigeminal nerves — one on each side of your face.

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).

When it is normal, tapping the mandible produces a brisk contraction. When abnormal, with upper motor neuron lesions, there is a hyperactive or repeating reflex (clonus). With nuclear or infranuclear lesions, the reflex is absent. Tell the patient you are going to test the ability to feel touch or pain on the face. The eyes should be shut.

2023年5月1日 · The trigeminal nerve (cranial nerve V; CN V) is a mixed sensory and motor nerve. It supplies the face via three branches of the nerve: from rostral to caudal, the sensory ophthalmic nerve (V1), the sensory maxillary nerve (V2), and the …

The Trigeminal Nerve is the fifth cranial nerve. It is also represented as CN V. It is the largest of all the cranial nerves. It is the most complex of all the cranial nerves due to it's extensive anatomic course. This nerve is a mixed nerve - having both sensory and motor fibres.

2025年1月18日 · Explore the anatomy, functions, and clinical significance of the trigeminal nerve (CN V). Learn about its branches, sensory and motor roles, and related disorders.
