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.
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 fourth ventricle Pons. Located in the superior orbital fissure. Innervates the lateral rectus, which abducts the eye. VII Facial
Olfactory nerve (cranial nerve 1) – smell; Optic nerve (cranial nerve 2) – sight; Oculomotor nerve (cranial nerve 3) – eye movement (except rotation) Trochlear nerve (cranial nerve 4) – eye rotation; Trigeminal nerve (cranial nerve 5) – sensation from the face and certain motor functions such as biting and chewing
The Edinger–Westphal nucleus also called the accessory or visceral oculomotor nerve, is one of the two nuclei of the oculomotor nerve (CN III) located in the midbrain. [1] [2] [3] It receives afferents from both pretectal nuclei (which have in turn received afferents from the optic tract). [4]
The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
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.

(through the medial longitudinal fasciculus) the contralateral oculomotor (CN III) nucleus (specifically the population of its neurons that innervate the contralateral medial rectus muscle). The pararaphal nucleus - one of distinct neuron population in the PPRF - projects to the flocculus of the cerebellum .
