Ganglion cells of retina[4]Transmits visual information to the brain; Located in optic canalIIIOculomotor nerveMainly MotorMidbrainOculomotor nucleus, Edinger-Westphal nucleusInnervates levator palpebrae superioris, superior rectus, medial rectus, inferior rectus, and inferior oblique, which collectively perform most eye movements; Located in superior orbital fissureIVTrochlear nerveMainly MotorMidbrainTrochlear nucleusInnervates the superior oblique muscle, which depresses, rotates laterally (around the optic axis), and intorts the eyeball; Located in superior orbital fissureVTrigeminal nerveBoth Sensory and MotorPonsPrincipal sensory trigeminal nucleus, Spinal trigeminal nucleus, Mesencephalic trigeminal nucleus, Trigeminal motor nucleusReceives sensation from the face and innervates the muscles of mastication; Located in superior orbital fissure (ophthalmic nerve - V1), foramen rotundum (maxillary nerve - V2), and foramen ovale (mandibular nerve - V3)VIAbducens nerveMainly MotorPosterior margin of PonsAbducens nucleusInnervates the lateral rectus, which abducts the eye; Located in superior orbital fissureVIIFacial nerveBoth Sensory and MotorPons (cerebellopontine angle) above oliveFacial nucleus, Solitary nucleus, Superior salivary nucleusProvides motor innervation to the muscles of facial expression, posterior belly of the digastric muscle, and stapedius muscle, receives the special sense of taste from the anterior 2/3 of the tongue, and provides secretomotor innervation to the salivary glands (except parotid) and the lacrimal gland; Located and runs through internal acoustic canal to facial canal and exits at stylomastoid foramenVIIIVestibulocochlear nerve (or auditory-vestibular nerve or statoacoustic nerve)Mostly sensoryLateral to CN VII (cerebellopontine angle)Vestibular nuclei, Cochlear nucleiSenses sound, rotation and gravity (essential for balance & movement). More specifically. the vestibular branch carries impulses for equilibrium and the cochlear branch carries impulses for hearing.; Located in internal acoustic canalIXGlossopharyngeal nerveBoth Sensory and MotorMedullaNucleus ambiguus, Inferior salivary nucleus, Solitary nucleusReceives taste from the posterior 1/3 of the tongue, provides secretomotor innervation to the parotid gland, and provides motor innervation to the stylopharyngeus (essential for tactile, pain, and thermal sensation)[citation needed]. Some sensation is also relayed to the brain from the palatine tonsils. Sensation is relayed to opposite thalamus and some hypothalamic nuclei. Located in jugular foramenXVagus nerveBoth Sensory and MotorPosterolateral sulcus of MedullaNucleus ambiguus, Dorsal motor vagal nucleus, Solitary nucleusSupplies branchiomotor innervation to most laryngeal and all pharyngeal muscles (except the stylopharyngeus, which is innervated by the glossopharyngeal); provides parasympathetic fibers to nearly all thoracic and abdominal viscera down to the splenic flexure; and receives the special sense of taste from the epiglottis. A major function: controls muscles for voice and resonance and the soft palate. Symptoms of damage: dysphagia (swallowing problems), velopharyngeal insufficiency. Located in jugular foramenXIAccessory nerve (or cranial accessory nerve or spinal accessory nerve)Mainly MotorCranial and Spinal RootsNucleus ambiguus, Spinal accessory nucleusControls sternocleidomastoid and trapezius muscles, overlaps with functions of the vagus. Examples of symptoms of damage: inability to shrug, weak head movement; Located in jugular foramenXIIHypoglossal nerveMainly MotorMedullaHypoglossal nucleusProvides motor innervation to the muscles of the tongue (except for the palatoglossus, which is innervated by the vagus) and other glossal muscles. Important for swallowing (bolus formation) and speech articulation. Located in hypoglossal canal

Answer 4

There are 12 cranial nerves, they are as followed;

(I) Olfactory

(II) Optic

(III) Oculomotor

(IV) Trochlear

(V) Trigeminal

(VI) Abducens

(VII) Facial

(VIII) Vestibulocochlear

(IX) Glossopharyngeal

(X) Vagus

(XI) Accessory

(XII) Hypoglossal

Answer 5

CN I - Olfactory, CN II- Optic, CN III- Oculomotor, CN IV- Trochlear, CN V- Trigeminal, CN VI- Abducens, CN VII- Facial, CN VIII- Vestibulocochlear, CN IX- Glossopharyneal, CN X- Vagus, CN XI- Accessory for vagus, CN XII- Hypoglossal, twelve cranial nerves. Functions: Olfactory I (smell) a sensory motor, Optic II ( vision) a sensory motor, Oculomotor III (eye movement) a motor, Trochlear IV (eye movement "polley" rotation of eye) a motor, Trigeminal V (mastication " chewing", nasal, propriaception of the tongue) mixed, Abducens VI (eye movement, control the lateral rectus muscle)a motor, Facial VII (controls facial muscles, taste receptors) mixed, Vestibulocochlear VIII (hearing, balance) special sensory, Glossopharyneal IX (taste, swallowing) mixed, Vagus X (taste, swallowing, connected to ear, largest cranial nerve), Accessory for vagus XI (talking, swallowing, shrugging) a motor, Hypoglossal XII (tongue movement). Here you have the twelve cranial nerves and their functions.
