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.
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.
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 ...

The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
The abducens nerve is most likely to show signs of damage first, with the most common complaints retro-orbital pain and the involvement of cranial nerves III, IV, V1, and VI without other neurological signs or symptoms. This presentation indicates either compression of structures in the superior orbital fissure or the cavernous sinus. [citation ...
Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V. Lateral to the parapharyngeal space lies the parotid space, which contains the parotid gland, the external carotid artery and cranial nerve VII. [1]
