The three major branches of the trigeminal nerve—the ophthalmic nerve (V 1), the maxillary nerve (V 2) and the mandibular nerve (V 3)—converge on the trigeminal ganglion (also called the semilunar ganglion or gasserian ganglion), located within Meckel's cave and containing the cell bodies of incoming sensory-nerve fibers.
Trigeminal: Both sensory and motor Pons: Three Parts: V 1 (ophthalmic nerve) is located in the superior orbital fissure V 2 (maxillary nerve) is located in the foramen rotundum. V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens ...
Some referred pain due to visceral sensations refer to dermatomes that send fibers to the same level of spinal cord. A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root ...
The ophthalmic nerve (CN V 1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V) , a cranial nerve . It has three major branches which provide sensory innervation to the eye , and the skin of the upper face and anterior scalp , as well as other structures of the head.
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. These nerve fibers ...
The trigeminal lemniscus contains two main divisions: The ventral trigeminal tract - consists of second-order axons from the spinal trigeminal nucleus. These fibers cross the midline and ascend to the contralateral thalamus. The dorsal trigeminal tract - consists of second-order axons from the principal sensory nucleus of trigeminal nerve ...

The trigeminal ganglion contains cell bodies of the pseudo-unipolar sensory neurons of the trigeminal nerve which extend their axons both distally/peripherally into the three divisions of the trigeminal nerve on the one end, and proximally/centrally to the brainstem on the other end; the trigeminal root extends from the trigeminal ganglion to the ventrolateral aspect of the pons.
