, In Which All Cranial Nerve first Name Letter included
 There Are Two Main Type Of Cranial Nerve Found
According To Number , They May Be “X” Or
“XII” In Number

4. Number Of Cranial Nerve ?
In Chordates :-
• Agantha (jaw less) = 8-10 pair cranial nerve
• Gnathostomata = 10-12 pair of cranial nerve
• In Pieces Chondrichthyes (Cartilaginous fish ) = 10 pair
• In Pieces Osteichtyes (Bony fishes ) = 10 pair
• In Amphibian = 10 pair
• In Reptilia = 12 pair
• In Aves (Birds) = 12 pair

8. Defects Of Cranial Nerve ?
 Olfactory Nerve (Cranial Nerve I) - Anosmia (loss of the
sense of smell), hyposmia (a decreased sense of smell)
 Optic Nerve (Cranial Nerve II) - Immediate monocular
blindness (partial or complete)
 Oculomotor Nerve (Cranial Nerve III) - Oculomotor
nerve palsy, including isolated and bilateral oculomotor
nerve palsies
 Trochlear Nerve (Cranial Nerve IV) - Injury to the
trochlear nerve can cause vertical diplopia on looking
downward which improves with contralateral head tilt and
worsens with ipsilateral head tilt

9. Defects Of Cranial Nerve ?
 Abducens Nerve (Cranial Nerve VI) - In a complete injury
of the abducens nerve, the affected eye is turned medially. In
an incomplete injury, the affected eye is seen at midline at
rest
 Trigeminal Nerve (Cranial Nerve V) - Corneal drying,
abrasions, and/or pain, decreased salivation, and, especially,
anesthesia of the forehead, eyebrow, and/or nose can occur
following TBI
 Facial Nerve (Cranial Nerve VII) - Complete or partial
paralysis of the face, hyperacusis, and/or an unusual or
impaired sense of taste can occur following TBI

10. Defects Of Cranial Nerve ?
 Vestibulocochlear Nerve (Cranial Nerve VIII) - Positional
vertigo is the most common problem, although tinnitus,
hearing loss, and deafness may also occur following TBI
 Hypoglossal Nerve (Cranial Nerve XII) - Dysarthria and
swallowing difficulties
