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 · While the trigeminal nerve (CN V) is largely a sensory nerve, it also mingles in the realm of motor supply. Unlike the other cranial nerves, the trigeminal nerve is quite large. It has four nuclei that send fibers to form its tracts and is associated with three separate branches.

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 anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches.

2023年11月3日 · The mandibular nerve, or the mandibular division of the trigeminal nerve (CN V3), is the third division of the trigeminal nerve (CN V) which innervates parts of the human face. It is a mixed nerve, meaning that it contains both motor and sensory fibers.

In neuroanatomy, the mandibular nerve (V 3) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V). Unlike the other divisions of the trigeminal nerve (ophthalmic nerve, maxillary nerve) which contain only afferent fibers, the mandibular nerve contains both afferent and efferent fibers.

2023年8月13日 · The mandibular nerve is the only branch of CN V to conduct motor axons to the muscles of the head and neck. The motor root of the trigeminal nerve joins the sensory component distal to the trigeminal ganglion and distributes its axons to the muscles of mastication :

The mandibular nerve (CN V3, Latin: nervus mandibularis) is the third and the largest branch of the trigeminal nerve (CN V), also known as the third or mandibular division of the trigeminal nerve. It is a large mixed nerve consisting of motor and sensory fibers.

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 …

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.
