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: Mainly motor Nuclei lying under the floor of the ...
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing. [1]
The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. It is classified as the eleventh of twelve pairs of cranial nerves because part of it was formerly believed to originate in the brain.

Cranial nerves originate directly from the brain's surface: two from the cerebrum and the ten others from the brain stem. [2] Cranial roots differ from spinal roots: some of these roots do not separate into individual sensory and motor roots, but can emerge from one fusion root instead; [3] of the eleven cranial nerves, four express this concept of fusion.

Ten of the twelve pairs of cranial nerves either target or are sourced from the brainstem nuclei. [14]: 725 The nuclei of the oculomotor nerve (III) and trochlear nerve (IV) are located in the midbrain. The nuclei of the trigeminal nerve (V), abducens nerve (VI), facial nerve (VII) and vestibulocochlear nerve (VIII) are located in the pons.
The oculomotor nerve, also known as the third cranial nerve, cranial nerve III, or simply CN III, is a cranial nerve that enters the orbit through the superior orbital fissure and innervates extraocular muscles that enable most movements of the eye and that raise the eyelid.
