It is the most&nbsp;voluminous nerve of all cranial pairs of the encephalic peripheral nervous system. It has its&nbsp;apparent origin in the anterior and lateral region near the middle cerebellar peduncle and its true&nbsp;origins distributed in pseudounipolar neurons of trigeminal ganglion “Gasser” located in the middle&nbsp;cranial fossa and sensory and motor nuclei located at different levels of brain stem. Of the three&nbsp;peripheral divisions of the trigeminal nerve, maxillary and mandibular divisions provide the sensory&nbsp;innervation of the structures that constitute the oral cavity, and mandibular division also supplies<br>motor innervation of the masticatory muscles, making it an essential anatomical reference for&nbsp;dentistry.</p><p><strong>Key words:</strong> Trigeminal nerve, ophthalmic nerve, maxillary nerve, mandibular nerve,&nbsp;gasserian ganglion, dermatome.</p> ER -
