Question

Create your own table. These are the column headings (in this order): cranial nerve #, cranial nerve name, functional category, specific function(s), specific site of brain origin or insertion, cranial foramen/foramina. For the rows, list all the cranial nerves. Be sure to include all branches of cranial nerve V and cranial nerve VIII.

Answer 1

Cranial nerves

Cranial nerve Name	Functional category	specific Function (s)	specific site of brain origin or insertion	cranial foramen/foramina
1 Olfactory	Olfaction, Smell, sensory	Olfaction, smell, Transmit the sense of smell from nasal cavity.	nasal cavity. Telencephalon Olfactory Epithelium	cribriform plate of ethmoid
2. Optic	sensory, retina vision	transmit visual signals from retina of eye to brain.	Retinal ganglion cell Located in optical canal	optical canal of ethmoid
3. Occulomotor	motor, Perform eye movement	Innervates the leveter palpebral superior is, Superior rectus, inferior rectus medial rectus and inferior oblique	Anterior aspect of mid brain, located in superior orbital fissure	Superior orbital fissure
4. Trochlear	eye ball movement, orbit	Innervates superior oblique muscle and eye ball movement	Superior orbital fissure, Enter to orbit, Dorsal aspect of mid brain	superior orbital fissure
5. Trigeminal A) opthalmic	Mixed type. Opthalmic trigeminal is sensory	Sensation from skin mucosa and region above orbit	Orbit, superior orbital fissure	Superior orbital fissure
5.B) maxillary	General sensory, sensation from skin	Sensation from skin and mucosa region from orbit to mouth	Pterygopalatine fossa	Foramen rotundum
5. C) mandibular	brachii motor	Muscle of mastication,	Infratemporal fossa.	Foramen ovale
6. Abducens	Abductor Mainly motor	Best abductor, Innervates lateral rectus of eye for abduct	Superior orbital fissure, Nuclei lying under floor of fourth ventricle.	superior orbital fissure
7. Fascial	Sensory and motor, Muscle of Fascial expression	Muscle of Fascial expression. Posterior belly of digastric muscle, stylohyoid muscle, staepedius muscle	Temporal bone, Cerebellopontine angle	Internal acoustic canal, to Fascial canal, and exit from stylomastoid foramen
8. Vestibulocochlear nerve A) vestibular B) cochlear	Vestibular branch carry impulse for equilibrium, Cochlear branch carry impulse for hearing	Hearing and balance	Cerebellopontine angle	Internal acoustics canal
9. Glossopharyngeal	Recieve raste from posterior 1 /3 Rd of tongue, Provide secret motor innervation to parotid gland, provide motor innervation to stylopharyngeus	Taste	Medulla	Jugular foramen
10.vagus	Supplies branchiomotor innervation to laryngeal and pharyngeal muscle, provide parasympathetic fibre to nearly all thoracic and abdominal viscera down to splenic flexure control muscle for voice	pharyngeal reflex, Pharyngeal muscle, Control muscle for voice, resonance and soft palate.	Posterior sulcus of medulla	Jugular foramen
11. Spinal accessory	control sternocleidomastoid muscle and trapezius muscle	branchiomotor control sternocleidomastoid muscle and trapezius muscle	Enter by foramen magnum exit by jugular foramen	Jugular foramen
12. Hypoglossal	Provides innervation for Muscle of tongue, and palatoglossal muscle	Swallowing, and speech	Medulla	hypoglossal canal
