trigeminaltieverkoston
The trigeminal tieverkoston (trigeminal nerves) is the fifth cranial nerve (CN V) in humans and is the main sensory nerve of the face, providing tactile, pain and temperature sensation to the ipsilateral half of the face, as well as motor innervation to the masticatory muscles. The nerve originates from the trigeminal sensory nucleus and the mesencephalic nucleus of the brainstem. It exits the skull through the foramen ovale, foramen rotundum and superior orbital fissure, forming three major branches: the ophthalmic (V1), maxillary (V2) and mandibular (V3) divisions. V1 carries sensory fibers from the forehead, scalp and upper eyelids, V2 supplies sensation to the lower eyelid, upper lip, nose and upper teeth, and V3 transmits sensory input from the lower lip, chin, lower teeth and anterior tongue, while also providing motor fibers that control the muscles of mastication, the tensor tympani and tensor veli palatini.
The trigeminal tieverkoston is crucial in oral proprioception, facilitating coordinated chewing and swallowing. Dysfunction or pathology
